Linux shared object (.so) segmentation faults

[inspiritive]

PB 4.10 running on Debian Sarge. The File and Database libraries immediately cause a segmentation fault when any function is used within a shared library (.so). I use exactly the same PB code in a linux executable on the same Debian system and it works without fail.

I also have exactly the same PB code using the File and Database libraries in a PB windows shared library (.dll) and it again works every time on Server 2003.

Are there known problems with PB shared libraries (.so) on Linux?

Any suggestions as to where to go from here?

Thanks,
