Doesn't seem that way: gcc -pthread -c  -DNDEBUG -g -O3
-Wall -Wstrict-prototypes -I. -I./Include  -DPy_BUILD_CORE
-o Objects/complexobject.o Objects/complexobject.c

Changing OPT in Makefile to include -ieee and recompiling
doesn't fix the problem, I still get a "Floating point
exception".

Can you tell whether you were compiling with -ieee?
