Hello to all of you,

at the moment, I'm despairing! I don't know why my code doesn't work.
Have a look:

void CMyClass::DoSomething()
{
try
{
DoItNow();
}
catch(...)
{
std::cout << "Exception caught!\n";
}
}

void CMyClass::DoItNow()
{
throw 5;
}


I compiled this code with -fexceptions and when I try to run it, after
the call of DoItNow(), the programm aborts with SIGABRT.

WHY???????????

Works Fine for me:
This is what I compiled:
$ cat X.cpp
#include <iostream>

struct CMyClass
{
void DoSomething();
void DoItNow();
};

void CMyClass::DoSomething()
{
try
{
DoItNow();
}
catch(...)
{
std::cout << "Exception caught!\n";
}

}

void CMyClass::DoItNow()
{
throw 5;

}

int main()
{
CMyClass x;
x.DoSomething();
}


This is my results:
$ g++ -fexceptions X.cpp
$ ./a.exe
Exception caught!

Hi!

I found my mistake... ;-) It was just a stupid error: DoItNow has been
called earlier in another function with no try/catch block: so the
thrown exception has never been caught.....

Thanks anyway!

Based on what you have shown, I'd have to say the problem is in the
code that you decided not to post.

Please show a truly minimal program that actually compiles and
demonstrates the problem, and perhaps you will receive better help.
