[ECOS] Erratic insight/gdb behavior

Hi... Thanks all for your help...


Turning the optimizations off ->>> No change
Giving App its own stubs  ->>> No change
Upgrading to Insight 5.2.1 ->>>> no change

I do believe it has to do with the fact that this code got put in ram....
That seems like its quite likely

Looks like debugging optimized code. Strange that you don't see it anywhere
else though.

Does it follow "more or less" the flow of execution. Then it is even more
likely that it has to do with optimization. If you see it stepping through
e.g. comments, object files and source code may have gotten out of sync.
Doing a complete rebuild is the easyest way to tackle this.

In the case of flash code, it may also have to do with relocation of the
code.
