For example, who is printing 'entering dbugS12_wait'? GDB 6.2 is old; you might try a current version of GDB. The output from 'bt' doesn't seem to ever find a valid stack frame.=20 Are you sure the program is even running, or that GDB is able to properly read its registers? When you print $pc, does its value look like a reasonable code address? Does the value of $sp seem to be a reasonable stack address?
