this is the error to look at! It means that the GC heap will be corrupted
quite easily.
Thanks, I'll have a go at that.
-fdump-tree-alias is also suspicious, hinting that that does more than just
print. (How many bugs here??)
Well, it only allocates some more heap memory for extra debug verbosity.
I think this can happen with other dumps as well.
Right. Anytime a -fdump-whatever changes behaviour, there's usually
some underlying memory issue elsewhere it's tickling.
