Trying to track down problem with packed.com from testsuite

Greetings, Gaius.

Here is an oddity:

[~/opt/gm2/testsuite]=> gm2-14 -c -O -fomit-frame-pointer 
-finline-functions -fiso packed.mod
[~/opt/gm2/testsuite]=> gm2-14 -c -O0 -fomit-frame-pointer 
-finline-functions -fiso packed.mod
[~/opt/gm2/testsuite]=> gm2-14 -c -O1 -fomit-frame-pointer 
-finline-functions -fiso packed.mod
[~/opt/gm2/testsuite]=> gm2-14 -c -O2 -fomit-frame-pointer 
-finline-functions -fiso packed.mod
gm2: internal compiler error: Segmentation Fault signal terminated

Basically, optimisation level 2 and above causes problems.

I am trying to chase down the problem but I have clue where the gm2 
compilation starts. Please inform me on which function to break.

Sincerely,
