I use seperate wave instances for each thread. Anyway, I'll try to get gdb running and debug the problem.

Thanks! Any hint is highly appreciated.

Nontheless there is another problem(?) in wave. Wave still uses the old filesystem interface, which makes it incompatible with code compiled with BOOST_FILESYSTEM_NO_DEPRECATED. That is a bug, right?

Ohh, I was not aware of that. How can I reproduce this?

Simply define BOOST_FILESYSTEM_NO_DEPRECATED before including boost.wave/boost.filesystem ;)

That's fixed now. (rev. 51679) Regards Hartmut
