I know 0.0 about the context here, but when I'm debugging and I see stuff
like that, what I do is severalfold:

a) run with asserts enabled if you're not already
b) make your stacks much bigger - eCos does NOT do stack checking
c) make your malloc heap much bigger (if that applies to your platform) -
   a failed malloc returns NULL, which can go undetected.
[Sorry if this is preaching to the converted...]

What's a bp-> ?  Is it an eCos data structure or part of GoAhead?
Those source files are references to allocation calls or pointers?
(If anyone else has more context here and can help properly, ignore me)
