A 32-bit GDB will not work on threaded programs on a 64-bit kernel; it's just broken. I believe the problem is a ptrace operation that is not properly emulated by the 32-bit compatibility layer. I'm afraid this is a kernel bug. -- Daniel Jacobowitz CodeSourcery -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
