Problems with exception handling in g++ version 2.95.4 [FreeBSD]

[Ravi I Singh]

Hello,

I tried to compile the following program from a C++ tutorial web
page:


// exceptions
#include <iostream.h>

int main () {
char myarray[10];
try
{
for (int n=0; n<=10; n++)
{
if (n>9) throw "Out of range";
myarray[n]='z';
}
}
catch (char * str)
{
cout << "Exception: " << str << endl;
}
return 0;
}

It core dumps when I try to run it. Any ideas? Thanks in advance.

Because the thrown exception is not caught, which results in a call to
std::terminate(), which in turn calls std::abort(). And that function
dumps core on most un*x systems. The problem is that you throw a const
char*, but catch a char*.
