Hi Mark,

thanks for the info - very useful to know it is to do with -g -gdwarf-2.

I wonder if you could try leaving -g but removing -ffunction-sections
-fdata-sections as these last two options have recently been
introduced to gm2.  It maybe that they conflict with the debugging
on this target (possibly) - in any case they are less useful than -g
(for most general cases),
