The problem is, that it's only this place in the code it fails.
I'm very causcious about performing "new" in C++ because of
memorymanagement trouble. So I don't do that much.
The code run's very smooth and fine when running a program (text), but
when programming as a plugin or part of a qt-application it's
reproducible both with gcc-4.1.1-r3 (gentoo) and gcc-4.2.2 (gentoo).
It's working fine with 64bit architecture but fails on 32 bit
architecture. Both systems running gentoo.
I could provide you with a complete package with everything with
makefile's and everything needed.
I've tried with a special boost-version (don't actually know the correct
version, but it fit's with the framework orocos) and with the 1.33.1
gentoo-distributed version.
Thanks for helping
Best regards,
Preben
