gcc-2.95.2 on SunOS5.6/Solaris 2.6: Internal compiler error in `change_address'

[Moritz Barsnick <barsnick at gmx dot net>]

Hi, dear gcc developers.

I am compiling a program called gseq (http://members.xoom.com/gseq/)
on Solaris 2.6 (SunOS 5.6) with gcc-2.95.2:

This is a beta version of gseq, it happens in the stable version
0.2.0 as well.

Here's the bug report according to instructions:

See above. It works if I leave away the optimization (-O2 or -O)!

Attached as "event.ii.bz2", call and results attached as "gcc.cmdline".

I once again add the note that, as stated above, removing the
optimization "-O..." convinces gcc/c++ not to abort with an error.

Greetings from Germany,
Moritz.   :-)
