It's hard to say what the problem is without more details. What is the
exception it throws? Is this only under the debugger? Xerces does throw
exceptions internally. Perhaps Delphi's debugger is showing these internal
exceptions.
Are you sure you are declaring the C++ function with the same calling
convention in Delphi and C++ (cdecl, stdcall, etc..)?
Your sample console program (written in C++?) which works calls the same
DLL that the Delphi program is calling?
Your C++ function should make sure that no exceptions are thrown out of the
function since Delphi probably wouldn't be able to handle them
correctly. You should wrap the everything in your C++ function in one
try/catch block to make sure no exceptions are thrown out of the DLL.
try { /* Xerces calls */ }
catch(...) { /* signal error condition by some other means */ }
