It would seem that the char array "exception" must be coerced to a string-object, but this is clearly not the case here. By the way, GCC 2.95 has the same behavior, and I didn't check the earlier versions. I have no certainty as to whether this presents a bug or just a feature, but in either case it is quite frustrating to deal with. >How-To-Repeat: #include <string> #include <iostream> void f() throw(std::string) { throw "exception"; } int main() { try { f(); } catch(...) { std::cout << "Exception caught." << std::endl; // The string exception does not get caught, // which aborts the program. } return 0; } >Fix: An obvious work-around it to use 'throw(const char *)' instead of 'throw(std::string)' as the exception specification for the function 'f'. Alternatively, we could use something like 'throw std::string("exception");' to raise the exception. >Release-Note: >Audit-Trail: >Unformatted: ----gnatsweb-attachment---- Content-Type: text/plain; name="bug.cpp" Content-Disposition: inline; filename="bug.cpp" #include <string> #include <iostream> void f() throw(std::string) { throw "exception"; } int main() { try { f(); } catch(...) { std::cout << "Exception caught." << std::endl; // The string exception does not get caught, // which aborts the program. } return 0; }
