I didn't look your change closely yet, but I confirmed that your
change doesn't break tcctest on both x86 and x86-64. I think we may
want to see a small code to reproduce the bug you found so that we can
add the code into tcctest to avoid future regressions. Could you show
the code the original tcc outputs wrong code?
Thanks!
