I think you might have hit the same problem I did when building
blibpq.dll for http://gborg.postgresql.org/project/pgtclng/

Mine would crash whenever a notification message was received (like primary
key create). The crash is in fprintf(stderr, ...), and the explanation I
got was that the I/O runtime wasn't initialized properly inside the Borland
DLL. But then, I was linking my BLIBPQ DLL with a MSVC-compiled program
(ActiveTcl), so maybe your case is different. The fix was easy: link with
Borland's "static" version of the runtime "cp32mt.lib" instead of
"cp32mti.lib".  But again: that was because I was using the BCC-compiled
DLL with a MSVC-compiled program. Your case may be different, and your
library name is different (CC3250MT), but look for a static runtime instead
of an import library runtime and try linking with that.
