This "garbage" is GDB telling you that you're program has
jumped into space :-)

How did you create this program?  On the Assabet with RedBoot,
RAM is at 0x00000000 and ROM/FLASH is at 0x50000000.  Your program
seems to have been built to run from ROM.

Note: the 'go' command is for programs built using eCos or GNUPro
with 'newlib' support.  It is not for stand-alone programs, in general.
