This is a known problem, -fschedule-insns should be avoided on x86.
config/i386/i386.c:2884
void
optimization_options (int level, int size ATTRIBUTE_UNUSED)
{
/* For -O2 and beyond, turn off -fschedule-insns by default. It tends to
make the problem with not enough registers even worse. */
#ifdef INSN_SCHEDULING
if (level > 1)
flag_schedule_insns = 0;
#endif
