graphviz 2.2 dot command in gcc-3.4 archive aborts

[Per Bojsen <per.bojsen@comcast.net>]

Hi,

the `dot' command from the graphviz 2.2 package in the gcc-3.4
archive aborts when run.  All I get is this message:

  Aborted

strace did not reveal much useful information.  I got the source
package intending to gdb this failure but quickly discovered that the
abort is apparently due to another GCC 4.0 optimization problem.  That
is, when compiled with '-g -O0' `dot' works and does not abort;
compiled with the default options which turns out to be `-g -O2' it
aborts.  I also tried compiling it with gcc 3.4 and it does produce
a working `dot' command even with the default `-g -O2' options.

BTW, a question for Andreas: Are we reporting the GCC 4.0 bugs
upstream?  Are the GCC 4.0 developers OK with reports like the above
or do they require narrowing down of the problem to a single source
file or function (which might be time consuming for a non-GCC expert)?

Thanks,
Per
