[dmd-internals] master branch brokenness

[Brad Roberts]

In the case of the freebsd failure, it was dmd itself crashing, not the 
generated code.  Walter's most recent checkin seems to have made it go 
away, though I'm not yet convinced the changes he made actually fix the 
problem.  Since I can reproduce it fairly easily, I'm going to continue to 
coax out a minimal test case of the problem to make sure.

For the OSX failure, it's one I've seen before, but it went away -- I 
don't remember if there was a direct fix at the time or not.  But it's 
definitly repeatable and needs attention.  It's not clear which layer is 
at fault, though quite possibly dmd since it's where there's been recent 
changes.

Later,
Brad
