Dear fellow Monks,

After doing a supersearch, a scan of all relevant docs and a grep on the .xs files of all the modules I've installed on my machine I didn't get a clue, so I'd like to seek your collective wisdom.

I'm currently writing a Perl module that interfaces to a C++ library. In several functions of this library, exceptions are thrown of a type I know, so in the XS code I use 

  try {
    ...
  } catch{MyException& e) {
    ...
  } catch(...) {
    ...
  }

to deal with it and to wrap the error message into a croak(...) for Perl consumption.

Upon testing it seems as if the C++ code throws the expected exception alright (this has been verified by the author of the C++ code), but in the XS code I can't catch that exception. However, something gets caught in the generic catch catch(...). I have turned on exception handling with the compiler option -GX.

Hence my question: has anyone successfully caught typed C++ exceptions in XS in this setup (NT 4.0 SP 5, ActiveState Perl 5.6.1 build 633, MSVC++ 6.0) or is there some advice you could offer?

Thanks in advance, -gjb-
