I see why other strchr does cause problems. Thanks, the patch to 
framestackwidget.cpp is now comitted, in revision 501878 
on /branches/kdevelop/3.4/languages/cpp/debugger

I'm afraid there is. The C standard gives the following prototype for strchr:

    char *strchr(const char *s, int c);

and:

1. No prototype in your compiler matches the above.
2. I'm pretty sure C implementation is not allowed to add extra overloads that 
change the meaning of programs.

I'd really suggest you report this as bug.
