[M3devel] endless exception loop on FreeBSD

[Olaf Wagner]

I'm trying to add pthread support to the FreeBSD4 platform.
My first tentative additions now lead to endless exception loops
once any error is encountered until the stack overflows.

Does anybody know what's wrong here? I'm not aware that I have
changed anything in this area.
