--- Comment #2 from ralphengels at gmail dot com <ralphengels at gmail dot com> 2011-04-19 09:41:45 UTC --- in all cases im afraid. i tried skipping over null names but the crash persists, no output either i just get the usual windows box with cpp.exe has stopped working. the reason why i noticed it in the first place was that codeblocks popped a warning about cpp not working every time it tried to parse from my project files. tbh. im not sure where the bug started from. i remember doing a build of an earlier svn version before release and there cpp was working but i cant remember the version number. i can upload the executable if you want to give it a try with debugging. ralph
