I've installed gcc 3.2.3 on my box and i can reproduce the problem.
the problem could probably be fixed but i'm not sure how yet.
If i take that code out i hit the next problem:
Synthesizer.h:318: Internal compiler error in fixup_var_refs_1, at function.c:
   1966
Please submit a full bug report,

i don't know how many more of these are out there.

so i'm not sure we can fix all of those. maybe we'll have to limit
ourselfs to supporting gcc 3.3.x and 3.4.x?
I'll try a few more things before i give up . . .
