OSX users out there? Serious bug (I think)

[Peter Alexander]

I use OSX. I have about 20kloc of D code, and it all works :-)  I 
have occasionally seen wrong code bugs in the past, but I've 
reported them all and from what I can remember they have all been 
fixed.

I can repro your issue. The illegal instruction is a 'popq' 
instruction called inside insertAfter, just after the destructor 
for the unnamed 'stuff' is called, before the function returns. I 
haven't looked into it further than that.
