I have been observing crashes in semi-random places around my D

was due to GDB disabling ASLR by default. And indeed, if I »set
disable-aslr off«, the crashes also happened within the debugger.
This is not totally surprising as Lion is the first OS X release to
include full ASLR for both 32 bit and 64 bit applications, but I have
not been able to track down what exactly goes on.
Any guesses what could go wrong here without additional details (I'm not
at all sure where to look right now)? Maybe something related to the OS
X-specific things like TLS handling?
David
Seems to be due to throwing exceptions, not TLS.

Yeah, can confirm that, all my issues seem to be somehow related to
exceptions to (even though in non-obvious ways sometimes).

This fixes the issue for me:
