I wonder if you are seeing the effects of a 128-bit long double. If it is, then -mlong-double-80 may help. I've had to use -mlong-double-80 in the past with some GNU software because it lacked support for 128-bit floats. The companion option is -mlong-double-128. Also see <https://gcc.gnu.org/wiki/Ieee128PowerPC>. Jeff
