--- Comment #72 from Martin Li=C5=A1ka <marxin at gcc dot gnu.org> ---
You will manage, it's not rocket science.

So please, add break point at the place it triggers the ICE and do:

(gdb) p &ptr1->x_help_flag
(gdb) p &ptr2->x_help_flag

and then watch for the addresses it prints:

watch *$number

where $number is returned from the 'p &' command. And then re-run the progr=
am
and you should see the:


Old value=3D...
New value=3D...

and you can print bt.=
