I am attempting to get ImageMagick to work properly using Cygwin DLLs. The C++ component is built as a DLL using the binutils auto-import feature and CVS libtool. The library works fine with the glaring exception that any C++ exception thrown from the library causes an immediate core dump. I have verified that C++ exceptions do work if they are not thrown from a DLL, and the library passes all tests (including C++ exceptions) if it is built as a static library. Do you believe that C++ exceptions should be working with Cygwin DLLs?
No, not yet. I don't know a whole lot about this, but I think that we need to have a gcc and libg++ that supports threads; and we don't have that yet. But that is supposedly a high priority. I think. I'm forwarding this message to Robert Collins; he may be able to clariy my confusion.
