segfault on Mac 10.5.8

[Digited]

Hi, LDC Devs,

Thanks again for a great compiler, i use it at home in opensuse linux
64bit.

At work in Mac Mini (Intel) with OSX 10.5.8 i have a stable segfault
on exit of every D app, compiled with today's ldc & tango trunks (llvm
2.6 prerelease).
Most D apps work, just segfault on app exit: minid's mdcl and minidc
do, but xfbuild doesn't.

If there's a way to find out more details (i dunno how), please let me
know.
