------- Comment #8 from oberlaender at fzi dot de 2010-04-21 13:42 -------
Just tested 4.5.0, which did not crash.
$ g++-4.5.0 -c -o bugtest.out -O2 bugtest.ii
$ g++-4.5.0 -v
Using built-in specs.
COLLECT_GCC=g++-4.5.0

Thread model: posix
gcc version 4.5.0 (GCC)
Also, all the 4.4.x versions work fine if I replace -O2 with -O1.
The question remains, what is going wrong with my various 4.4.x tests, and why
did it work for Jonathan?
I've circumvented the problem in my piece of software for now by going from -O2
to -O1, as I don't feel like rebuilding everything against 4.5 just yet. :)
But at least according to my tests, the problem is present in all 4.4 releases.
Can anyone else reproduce the error?
Thanks and best regards,
Jan
