ditto, I suspected a known bug in my gcc version which broke xchg

was too many config tweaks ago to get back to last time I had it working
that well)

Like disabling "Optimize for size" in the config?
Just tried, didn't make any difference.

it's clearly one of those fun and subtle bugs :(

*sigh* :(


p.s.: someone let me know if i should keep everybody on cc!
