When you are doing this, do you have ANY windows open (esp the register 
window -- there is some bitrot in there that I have to address)?

If you don't have any other windows open (just console & source), then I 
recommend trying to reproduce with gdb.

Run "[arm-*-]insight -nw" and try it again. If the internal error pops 
up again, it is, as you suspected, a gdb problem. Grab the backtrace 
from the coredump and either file a bug in gdb's bugzilla or ask on the 
gdb@ list.
