Please open a bug report. They also fail on Linux with SSE fpmath:

bash-3.2$ /export/build/gnu/gcc/build-x86_64-linux/gcc/xgcc
-B/export/build/gnu/gcc/build-x86_64-linux/gcc/  -w  -Os
-fno-show-column -c  -o
/export/build/gnu/gcc/build-x86_64-linux/gcc/testsuite/gcc/BUG11.o
/export/gnu/src/gcc/gcc/gcc/testsuite/gcc.c-torture/unsorted/BUG11.c
-m32 -msse2 -mfpmath=sse
/export/gnu/src/gcc/gcc/gcc/testsuite/gcc.c-torture/unsorted/BUG11.c:
In function 'foo':
/export/gnu/src/gcc/gcc/gcc/testsuite/gcc.c-torture/unsorted/BUG11.c:6:
