Mateusz,

I have come to the conclusion that part of the CppUnit
test harnass (TextTestRunner?) is in fact trapping all
exceptions within the test operations.   So, this is a
need that is already anticipated by the test harnass.

Of course, that doesn't explain why things aren't working
for you. I too have had very anomolous results on Linux
when unexpected exceptions are fired.  I was unable to
determine why, and I suspect there is something
questionable in my build environment.  Perhaps a
flaw in the version of g++ or the c++ runtime options
in place.

Hopefully we will learn more in the future.  In the
meantime, if I step through to track unexpected
exceptions, and "fix" them I find the unit tests
(for fdogdal in my case) do work ok on Linux.

Best regards,
