-march=core2 implies -mmmx, so this test should be executed with -mno-mmx.
Using v4hi, or anything that is defined with vector_size (8), like:

typedef short v4hi __attribute__ ((vector_size (8)));

from the test, uses MMX registers (when enabled). When MMX register is touched,
it blocks whole x87 register stack untill emms is executed.

I'll add -mno-mmx for the testcase.
