I've just done this myself, using the function handler() from a previous version of libgfortran/runtime/compile_options.c and putting back the essential part. With the attached patch, I get: Program received signal 8 (SIGFPE): Floating-point exception. Backtrace for this error: #0 0x805891F in _gfortrani_show_backtrace at backtrace.c:261 #1 0x804951F in _gfortrani_backtrace_handler at compile_options.c:93 #2 0xFFFFE3FF #3 0x80493B3 in foo at gfcbug113.f90:8 #4 0x804940B in backtrace at gfcbug113.f90:3 written to stderr when -fbacktrace is active, otherwise nothing.
