I am having trouble debugging a simple program on B19. I have tried bot the
default compiler tools and the EGCS tools but I get the same behavior in
either case. The program works more or less correctly (it gets stuck in a
endless loop somewhere) but when I run it under gdb and hit the start
button I get this:

Here is the Makefile

What am I doing wrong ?
