Darwin 32 release broken (in uni.d)

[monarch_dodra]

It looks like the darwin 32 release is broken at the phobos 
unittest stage. It would appear the breakage is in the uni.d 
debug step:
make[1]: *** [generated/osx/debug/32/unittest/std/uni] 
Segmentation fault: 11

I don't think it is the new uni module that is responsible, since 
it worked fine when it was merged.

I haven't pinned down which pull triggered the breakage, but I 
figure the first step to getting the release fixed is to announce 
it as broken. Or I should file a report instead?
