Hi Diego,
did you have a look at this one?
This makes -fopenmp almost unusable for the C++ frontend.
PR 26032 is probably a duplicate of this one.
I stumbled over the bug independently, too.

I still get a segfault for the testcase in comment #6.
This is revision 110467 on x86_64-unknown-linux-gnu.
Note, that this is with the C frontend:
gcc -fopenmp --param ggc-min-expand=0 --param ggc-min-heapsize=0 -c PR25990.c

Ah, yes. I had failed to notice the failure is on x86_64. Sorry about that.
