I can locate the problem in the code, that the problem is only produced in this class, in which C and C++ code is mixed.
I use a call of the libxml2, which is a C library. The code works under Linux and OSX.

I use for my project only Cygwins g++ / gcc, not MinGW or MSVC, so do you know any things about this? On some websites
there are the -fexceptions flag is seen, but if I set them, the problem isn't be solved. 

I have try to catch my thrown exception with catch (...), catch (myexception e) or some other catches, but the exception is not
be caught. Should I recompile all my libraries with the -fexceptions flag or only my code? Are there other flags for correct 
exception handling under the Cygwin gcc / g++?

Thanks

Phil
