Hi, 
we have confirmation now from hp, that they could reproduce the problem
(pls. see below).
We here decided to switch to a newer gcc compiler version.
And doing so we will also switch to a newer boost lib version.
Actually we already tried the 1.41.0 with the old gcc-3.4.4.
But for that there was a not backwards compatible change in boost::spirit impl. and API.
So as we don't have time to adapt our application, i guess we need to use the 1.40.0?
cheers,
Frank

I ran the test case from the GCC bug report using GCC 3.4.5 and Boost

1.33.1 and was able to reproduce the problem on my system.

Generally, I recommend using the most recent GCC version available.

The FSF is not going to fix anything on the 3.4.* branch, this branch is

considered 'dead' and is no longer being maintained.
