Frame #1 suggests that this is a glibc issue. gfortran will translate ieee_support_halting into _gfortrani_support_fpu_trap. % nm ieee_exceptions.o | grep _trap U _gfortrani_get_fpu_trap_exceptions U _gfortrani_set_fpu_trap_exceptions U _gfortrani_support_fpu_trap % nm fpu.o | grep _trap 0000000000000000 T _gfortrani_get_fpu_trap_exceptions 0000000000000000 T _gfortrani_set_fpu_trap_exceptions 0000000000000000 T _gfortrani_support_fpu_trap The code in libgfortran/runtime/fpu.c appears to pull in architecture dependent code via /* We include the platform-dependent code. */ #include "fpu-target.h" I don't know where or how powerpc64 sets up fpu-target.h.
