RE: [Mingw-users] Structured Exceptions, C++ Exceptions, DLLs, oh my!

[Andrew B. <ab...@ee...>]

One addition to this solution (which works, btw, thanks!) re: DLLs. The
_catch1 function must be in the same DLL as the try-catch clause, or the
C++ exception doesn't make it out of the structured exception handler to
the C++ exception handler. Is that a known flaw of C++ exceptions
(crossing DLL boundaries) or do I need to add some flags when I compile?
