Your program is almost certainly buggy. Please send general how-to-program
questions to the gcc-help list. This list is about how to write and modify
the internal program code of the compiler itself, not about how to write
programs *with* the compiler. You should only report it here if it was the
compiler that segfaulted, or if you have some reason to beleive the compiler
mistranslated your source files and generated incorrect code that caused the
segfault.

Nope, it most likely means you have a bug to fix. Just because the crash
occurs in a library function doesn't mean the library is at fault; 99 times
out of 100 it means you passed invalid values to library functions, or
overwrote vital heap or stack memory where the library function had some
storage.
