#86 Error on rendering highlighted characters

[Frederick Zhang]

Typing the codes in the picture will make C::B crash. Some other codes may also cause the same problem.

Environment:    Windows 8.1
Code::Blocks:   r10020 from svn
Compiler:       MinGW-w64 x86_64-4.9.1-release-posix-seh-rt_v3-rev3 and TDM-GCC x86_64 4.7.1
Boost:          1.56
wxWidgets:      3.0.2
FortranProject: 1.2 from svn

PS: the code:

#include<stdlib.h>
#include<iostream>
using namespace std;

void plus()
{

}
int main()
{
    plus(
}

[ollydbg]

It looks like you build C::B against wx 3.0.2? Can you try wx2.8.12, as I know, C::B svn build against wx 3.x is not stable yet.

[Frederick Zhang]

Ok, but which project should I use? There's no "CodeBlocks_64.cbp"

[ollydbg]

Oh, sorry, I remember that under Windows, C::B link against 64bit wx2.8.12 is also not quite stable. So, there is not such file, currently, fixing the crash problem as you described is the right thing we should do.

[ollydbg]

Can you try to disable the Codecompletion plugin, and see whether this bug could gone, thanks.

[Frederick Zhang]

Yes, it's gone with the code completion disabled.

[ollydbg]

Can you run C::B under debugger, and see where the crash come from? You can debug C::B under C::B.

Here's the screenshot and the debugger log.

OK, what is the crash backtrace?

[Frederick Zhang]

is this what you want? sorry that I'm not good at C/C++

[ollydbg]

Thanks. Backtrace under GDB means the call stack. I just want to see what is the call stack when this crash happens.

[Teodor Petrov]

This gives no info. Can you go to the Settings -> Global variables -> cb_release_type and set it to "-g -O0", then rebuild and retest?

[Teodor Petrov]

Still not helpful. There is no entry coming from cb's sources.

[Teodor Petrov]

Does this still happen with trunk?

[Teodor Petrov]

Closing due to inactivity.
