hi,
i'm currently testing gcc-4.4.1-20090427 on my large c++ codebase.
the application uses threads, contains over 100+ shared components
and the tested debug build (-O0 -g2 -fpic) needs over 2GB of disk space,
so creating reduced testcase at this point isn't trivial thing.
i've observed that boost-1.38.0 and/or stlport-5.2.1 used in this project
are broken by gcc-4.4.1 and trig abort() in glibc malloc checker.
application linked with boost/stlport compiled with gcc-4.3 works fine.
after few hours of valgrinding i've noticed following errors
with gcc-4.4.1/boost/stlport which don't happen with gcc-4.3.
