How to debug a 64bits application?

[Miroslav Novy <mnovy at ales dot cz>]

I used gcc 3.2.1 (downloaded as a package from Sun freeware) with parameter -m64 (generated
code for 64-bit environment) on OS Solaris 2.8 on UltraSPARC-IIe cpu (SunBlade 150) and I can't
debug it.

Example:

#include <stdio.h>

int main (int argc, char *argv[])
{
  printf ("program: %s\n", argv[0]);

  return 1;
}

bash-2.03$ gcc -g -m64 -Wall foo.c -o foo

bash-2.03$ ./foo
program: ./foo

bash-2.03$ gdb foo
