Thanks, I had seen that also. I am already passing in the unstripped 
executable when I call gdb so I think it should have been set already. I 
try showing the architecture but it just reports arm which is not 
specific enough to give me a clue what is wrong, I assume it is some 
mismatch in expected floating point registers.
