Probably, you can get more info as follows: Run cc1 under gdb and set args. Put a break on var-tracking.c:507. Probably, the fault occurs on first call to remove but this can be checked by running program with ignor set to a large number. When program hits break, disassemble around break with "disass $pc-32,$pc+32". Single step forward. If code branches, disassemble new code. Do this until you hit fault. This should show where/how things go wrong.
