>Description:
I wrote a little test program that reports I didi make a 64 bit piece of code, but when main() returns, it core dumps.  If I add an "exit( 0 );",  it's happy.  Admittedly, I was rushing the gcc build.  Just for fun, I tried to gdb the core file, and it does not like the 64 bit sparc core file from code I linked with the Sun 64 bit linker:

#include <stdio.h>

main()
{
        printf( "%d\n", sizeof( long ) );
}
