Crash on wxString related function frequently

[snakesin]

Hello everyone,
I had encounter a crash problem frequently, the call stack in crash reports are almost point the problem to wxString.
But I can not figure out the root cause of this issue. This codeblocks was use wxWidget 2.8.10. thanks.

What about sharing some basic info like OS, CB, compiler versions?

We're magicians level 0 :-P

[snakesin]

Sorry for incomplete information  :?
The OS was fedora 11
code::blocks 8.02
compiler was gcc 4.4.0

I had add some plugin to make my c::b meet my requirement. Maybe I misuse the wxString in some places ?
Does it caused by the difference of unicode or other encoding ?

[oBFusCATed]

Can you try a nightly build, the encoding detector has been improved/changed after the release of 8.02 ...

If you use threads, make sure not to access gui-elements directly from inside the thread and be aware that wxString is *not* threadsafe.
