Re: SR getting corrupted

I don't think bt actually works correctly on mspgdb (at least it never has for me in the last 6 years). I recommend you check the sp directly with the "info registers" command (or simply "i r"). The sp is r1 if I recall correctly.

Then you can dump the memory in your stack and do something of a manual backtrace - if you know the current pc (again available through the registers) and you have a full assembly listing it should be possible to spot the return addresses in the stack (or simply check every word, if it corresponds to a location in code just following where you called a function then it is likely a return address - note I've only ever done this in my own software which I know back-to-front and it is all 16bit addressing, no msp430x).

Or, you could try mspdebug - I think it has many debugging features and probably has a working "bt" command (I am still use mspgdb though so I'm not sure).
