RE: try-catch exception

Hello-gcc,

I have a C++ library linked to C executable. C++ library is unable to
catch the exception in the try/catch block. I've also tried
"-fexceptions"  compiler switch and yet the program core-dumps with
SIGABRT signal. Any reason why exception handler is being invoked ?

"terminate called after throwing an instance of 'int'
Aborted (core dumped)"

I have a sample code snippet below.

int main1 () {
 try
 {
   throw 20;
 }
 catch (const exception &e)
 {
   cout << "An exception occurred. Exception Nr. " << e.what() << endl;
 }
 return 0;
}

You throw an int and try to catch a std::exception, so it isn't caught.
Try catch(int) or catch(...).
