I could be wrong, but I am not sure if anyone can really help without 
seeing some sample code.

In any case, you may wish to try your tests again using boost 1.42 if 
only because there were some exception related fixes that made it into 
the iostreams library in this version.

For details on the iostreams fixes in this release, see:
