Testcase is as simple as this, compile with -O2 (can be triggered in a cross
compiler):
void foo (unsigned u)
{
if (u != 0x34303365)
bar ();
}
Result may vary, either segfault in get_last_value_validate(), or ICE in
copy_rtx, at rtl.c:314, or abort() in libc after free, depending on how
compiler is invoked (from gdb or not), amount of enabled checking and host
machine.
