Does someone know whether the DMC libs are capable of multithreading.

Especially which of them are not.

I use multithreading and under circumstances I cannot specify the
application
crashes by jumping to address $00000000.

Yes, they are all multi-threadable (the Win32 libraries).

The non-Win32 libraries are single threaded.

These kinds of problems can be really hard to find. It sounds like your stack return address is getting overwritten with a 0. One way to try and track this down is to heavilly instrument your code, writing invariants for each struct and using the DMC++ design by contract extensions.
