Hi, https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=146810 Inferior ENV{"LD_LIBRARY_PATH"} and/or ENV{"PATH"} may get ignored by solib_open() resulting in Error while mapping shared library sections: libc++test4dl.so: Success. and afterwards while calling a function from the shared library it crashes: (gdb) call randomthing() Program received signal SIGSEGV, Segmentation fault. randomthing () at c++test4dl.cxx:3 3 void randomthing() The program being debugged was signaled while in a function called from GDB. Trivia NULL vs. "" check issue. Regards, Jan Kratochvil
