Code autocompletion hangs Code::Blocks

<< < (2/4) > >>

oBFusCATed:
I cannot reproduce it here.
Can you try to reproduce the problem using just base types?
The uintXXX_t types are typedefs defined in some header the compiler knows about.
For example use

--- Code: ---typedef int myint32;

--- End code ---

Also can you post a backtrace of the hang using gdb?

Hi,

I cannot reproduce it using custom types. I was able to reproduce the problem using uint16_t and uint32_t types, with uint8_t nothing happens, No #includes.
It seems that codeblocks internally handle those types differently.

I made a screencast trying to reproduce the problem and attached a backtrace using the debian version (they had a -dbg package for codeblocks).
I made the screencast with factory settings, in the middle I disabled the symbol browser and the "parse documentation" checkbox in the editor settings.
If you cannot reproduce the problem make the edit pane smaller and try again.

Here is the screencast, please download it and play with vlc or other player, the webplayer doesn't owrk (at least for me)

I compiled codeblocks from sources and found that it hangs in the following line

ccmanager.cpp

--- Code: ---bool UnfocusablePopupWindow::Show(bool show)
{
    bool rv = BaseClass::Show(show); // in this call C::B hangs

--- End code ---

with the following call stack

This sounds like a bug in UnfocusablePopupWindow under Linux.

So I should write a bug report to wxWidgets, I don't think they will take me seriously with this use case, For now the workaround is to disable the feature.
