Is it also by you? It crashes in ~x86 (Pentium M) and ~amd64.

I don't know if it is a C::B bug, wxGTK or a local corrupted Gentoo :?

[Biplab]

Looking at the crash log it seems C::B is unable to load the required xrc files. Just do a clean install (which should re-create the zip files) and see if it persists or not.

[alchemist]

Ok, I'lll uninstall, clean the SVN files and try again

Hello,

Someone at the Gentoo Forum gave me a work-around:

Code Select Expand

G_SLICE=always-malloc codeblocks and this works!

G_SLICE is a glib parameter, so no problem with C::B or wx

[Seronis]

Im an XP user, but could you explain what that option does?  Been considering getting a 2nd HD for gentoo or ubuntu for dual boot option and would like to know what potential problems id have using C::B there.

[alchemist]

Hello,

This is a GNU glib issue, encountered in Gentoo Linux. Maybe the chosen compilation flags changed that option, so that C::B crashes.

Glib is not used for the Windows build (only wxMSW and mingw G++)

[Anubis]

This is a confirmed GTK issue, actually.   (new GTK version release just before Gnome 2.20 has issues, thus having compiled wxGTK against one of the newer GTK versions will cause this crash in C::B).

At least, that's my understanding.

[alchemist]

Works fine now, since I upgraded wxGTK to version 2.8.6
