Disabling _FORTIFY_SOURCE fixes SIGFPE in zipl: Program received signal SIGFPE, Arithmetic exception. memcpy (__n=7976, __os=<optimized out>, __od=0x3fffdff60c0) at /usr/include/fortify/string.h:53 53 return __builtin_memcpy(__od, __os, __n); disassebly shows that the exception happens on the jump instruction to memcpy. Work around it by disabling _FORTIFY_SOURCE for zipl.
