I think I have circled the problem:

* It is not in cpp.
* It appears only when using the newest version of CWSDPMI (release 3)

I've also compiled the svasync library.
Running the test program of svasync (term.exe) produces an 
error message (no crash) while locking dpmi-memory. (To be
precise: __dpmi_lock_linear_region() returns -1 where it 
shouldn't. This might be a good start for debugging.) 
Changing CWSDPMI from release 3 to release 2 removes this 
problem too.

Current work-around: use CWSDPMI release 2.

Regards,

Tony
