C::B crashes after Debug - Next Line
oBFusCATed:
Please enable full (in the debugger's settings) and post it.
ollydbg:
I see such kind of issue one or two years ago when debugging C::B, but I don't see them right now, I believe it is a bug in GDB or GCC, but they are already fixed. ;)
benezan:
I also have the impression that somehow my installation of Mingw is broken. But I feel a bit overwhelmed fixing it. I tried to install the latest version of C::B. Here it's said that codeblocks-13.12mingw-setup.exe is recommended and that it comes with a stable, precompiled version (4.7.1) of MinGw.
When I install that my program doesn't run at all. I get an error message "_gxx_personality_v0 could not be located in the dynamic link library libstdc++-6.dll". I googled and found some answers but, no , I don't have a 64 bit system, my compiler executables are set correctly (g++, not gcc) and I assume that the version of the dll should fit the compiler if it comes in the same archive. The computer was blank (no other version of C::B and no other compiler was ever installed on it) and I even searched the hard disk for different versions of libstdc++-6.dll, none found.
I gave up and completely deleted the Mingw installation. I re-installed from my archive "mingw-get-inst-20120426.exe" I saved last year. Surprisingly when I enter "gcc -v" the new installation displays 4.6.2 where on my other computer it says 4.7.2 (GDB 7.4 as opposed to 7.5). I suspect this has something to do with that's not a real archive but a "get-inst" that downloads from the internet... but anyway - now it works, I mean it compiles and runs with C::B V13.12. But I still get the same debugger error "input/output error...". :(
So I think Ollydbg is right, it's not a C::B bug but a GDB/GCC problem. So please excuse my ignorance, I know this question has surely been asked many times before: "Where do I get a stable version of MinGw and how do I install it so that it works?" :-\
The precompiled bundle "codeblocks-13.12mingw-setup.exe" doesn't seem to work. I don't want the latest "experimental" version (TDM 4.8.1) but the stable one, if possible. Can I expect the "_gxx_personality_v0" issue to be fixed if I build it on my own insead of using the precompiled one? Thank you very much for your patience.

MortenMacFly:
Check you PATH environment variable and compiler settings in C::B. It looks like you have multiple instances of different compiler versions installed that conflict (which is normal in the case of multiple version in the PATH).
If unsure, search for gcc*.* across your whole PC.
