Windows Nighly Recent crash issue for Environment setting.
« on: June 08, 2015, 07:18:02 pm »
Edit: The crash NO longer seems to be caused by EnvVars plugin.
Doing these steps cause a crash by themselves; but, only when the EnvVars plugin is enabled
Settings -> Environment
Click on OK

Attached new crash log from CodeBlocks_svn10320


Tim S.

In contrast to the nightly offered below, this also includes the crash handler, so its probably better suited for testing and reporting.

Crash handler works.

In the last 3 or 4 nightly a Windows crash has started. Edit: No Problem on svn10253; has problem on svn10314/svn10311
Using the EnvVars plugin, if you have 2 added configs.
Trying to change from one added config to something else causes a crash.

Settings -> Environment
Environmental Variables
Then try to change the selected configs; it sometimes crashes before I try to change the selected config.

Are you sure you have a clean build of CB?

No, but, I do NOT think it matters since I am getting the problem on the nightly download.

Downloading  killerbot most recent build right now.

killerbot most recent build (04 June 2015 build (10320)) has the same problem.

Doesn't happen on linux with rev10323, so I can't help much.

I can confirm the crash with the latest nightly (rev10320). It doesn't occur on my custom x64 build (rev10305).

What compiler version is used with your custom  x64 build?

I am starting to think it might be a Compiler and/or wxWidgets bug.

I have failed to see the problem using TDM MinGW GCC 4.7.1 under Windows 7 64 bit Home Pro.
But, I do see it under  MinGW GCC 4.9.?2? under Windows 7 32 bit Ultimate.

tdm 4.9.2

I don't think that's compiler or wxwidgets related, I believe it's because of a change somewhere between 10305 and head revision. I'll rebuild my local trunk to the latest head and try to see where it crashes with drmingw. It doesn't always catch the crashing function though.

Why don't you use gdb to find where it crashes?

Well, I think it's because drmingw gives me a report whether the crashing program is under a debugging session or not. Anyway gdb spit the backtrace below:

Can you try to revert rev 10309 and see if the problem goes away?

Tried that on my Laptop and the problem was NOT there; then I added it back and the problem was still gone.
That why I guessed GCC 4.9.2 was the cause; but, using MinGW GCC 4.7.1 on my desktop and it still had the problem.
Now going to revert rev 10309 on my desktop to see what happens.

Reverting the changes in rev10309 fixes the crash issue. So I think it's commit 10309 that results in the crash. I've come to believe that this is actually a wxwidgets problem considering it's the windows platform that's affected but I can't step into the 'check' function to see what's going on. Is there a way to do that or gdb just can't step into virtual functions?

Can a C++ expert explain how sel can hold the result of new EnvVariableListClientData(key, value)?

Edit: Or does the sequence operator "," do something different in C++ than I think it does?

Tim S.

Code: [Select]
    int sel = -1;
    if (lstEnvVars)
    {
      sel = lstEnvVars->Append(key + _T(" = ") + value, new EnvVariableListClientData(key, value));
      lstEnvVars->Check(sel, bCheck);
    }

The crash stopped when I fixed the seq. operations.
