This happens on OS X now and didn't before:

very same as on FreeBSD-64. for some reason my compiler on macosx is still happy.

I suspect some typist change is guilty.

[waywardmonkeys]

I would also consider potential candidates to be the threading changes in the C backend or optimization levels.

OS X is fine for me on my Lion (xcode4) box, but not on Snow Leopard (xcode3, my laptop).

[waywardmonkeys]

This was due to the setjmp / longjmp changes. Fixed now.

oh cool, will retry the FreeBSD-64 once I've some spare time! Thanks a lot, @waywardmonkeys
