Dear Yves,

I've tried to compile this plugin on a more recent compiler. I suggest to apply the patch that is attached to:
- get rid of the deprecated auto_ptr
- simplify the singleton pattern
- fix an compiler error in non-PCH builds due to missing #include <iostream>

The patch applies to 2 files on the staging branch only: cclogger{.h/.cpp}.

I applied your patch. Thank you!

Maybe apply it also on the builltin codecompletion plugin since it has the same file?

Hi, your last commit seems to have fixed my previous crash.
But on project closing (like the codeblocks project file) i get sometimes this crash report:

And reversing the conditions speeds things quite a bit. :)
Checking f->compile is quite a lot faster than calling FileTypeOf and most of the times it is false.
This change will land in master/head soon.

Sorry this is in compiler.dll and not in the clanglib plugin.

   632:     if (data->errorIncludes.find( includedFileName ) != data->errorIncludes.end())

I wrote a little sikuliscript to reproduce this issue by continuously opening and closing projects and the same trace as you show here is there on a CentOS7 system. I think the problem comes from the fact that wxString is not thread safe since it is doing a double free of the wxString data and I pass these wxString objects between threads. Normally I try to keep these wxString objects created&destroyed on the same thread or deep-copied if they need to be handed over from one thread to another. It's probably better if I switch to std::string for anything that crosses these threads and force c++11 to assure thread-safety. I'll make a POC and see if that improves reliability.

wxString in wxWidgets 2.8.12 is not thread safe, and it should be thread safe in wxWidgets 3.0+, because it use std::string, and std::string is atomic reference counted.  There is same issue in the native CC, and it's hard to solve unless we move to wx3.0+.

What does POC mean?  Prove of Concept?

If some piece of memory should be reused, turn them to variables (or const variables).
If some piece of operations should be reused, turn them to functions.
If they happened together, then turn them to classes.

Hi, sorry i forget to answer and report my findings:

Code

   631:     clang_disposeString(str);
   632:     if (data->errorIncludes.find( includedFileName ) != data->errorIncludes.end())
about this crash: I replaced the function
Code
wxString::FromUTF8(clang_getCString(str))
with (pseudocode, have the actual code at home)
Code
wxString clang_to_wxString(clangstring* str)
{
if(str == nullptr)
return wxEmptyString;
else
return wxString::FromUTF8(clang_getCString(str));
}

and i have no crashes with this bt so far, but i tested it not that much.

you will note that this is a stack overflow crash. And the stack is nearly 210 calls in the clang library. Actually it is in the event handling code of wx 210 calls. So i think there is somewhere a recursive event loop. So this is a clang problem.
I am not this familiar with the event system so i didn't looked over it to much...
This is underlined by this messages from the bt I think this is a clang problem because of this returning bt information:
Code

   223:         return true;
   224:     for (std::vector<ClangPluginComponent*>::iterator it = m_ActiveComponentList.begin(); it != m_ActiveComponentList.end(); ++it)

A other problem i noted quite frequently is if you open a new cpp file, enter code at the end of the file (no line text after the last line code) and this code has errors, so they get reported by the instant error reporting wxScilite will report some error about writing past the buffer, or writing non printable characters or something like this. I am actively investigating in this if i find some time.
This is no crash, but a assert()

I don't recall how i can reproduce this, but i will report as soon i am able to reproduce it...

wxString in wxWidgets 2.8.12 is not thread safe, and it should be thread safe in wxWidgets 3.0+, because it use std::string, and std::string is atomic reference counted.  There is same issue in the native CC, and it's hard to solve unless we move to wx3.0+.

What does POC mean?  Prove of Concept?
Yes, Prove of Concept, I adapt some operations that are used in the project load&unload scenario that I was using and see if this specific problem is fixed.

This is no crash, but a assert()

I don't recall how i can reproduce this, but i will report as soon i am able to reproduce it...
Sounds familiar, I fixed something similar in the past, but it was only reproducible on Windows. Sadly I don't test it often on Windows. It's hard enough as it is to test on wx28, wx30, ubuntu, centos, ...

    I would also verify "f"not being NULL:
    if (f && FileTypeOf(f->relativeFilename) == ftHeader &&
    ...especially on shut-down.


Sorry this is in compiler.dll and not in the clanglib plugin.

you will note that this is a stack overflow crash. And the stack is nearly 210 calls in the clang library. Actually it is in the event handling code of wx 210 calls. So i think there is somewhere a recursive event loop. So this is a clang problem.
I am not this familiar with the event system so i didn't looked over it to much...
This is underlined by this messages from the bt I think this is a clang problem because of this returning bt information:
Code

   221: {

   223:         return true;
   224:     for (std::vector<ClangPluginComponent*>::iterator it = m_ActiveComponentList.begin(); it != m_ActiveComponentList.end(); ++it)
[Edit:] correcting the hypothesis

No it is not a recursing problem. On some operations wx is processing events for a short while, thats why you see them stacking up.
