Hi Aaron,

Please try applying the attached patch. It will change the seg fault
into an intelligible error message:
BFD: Unable to find equivalent output section for symbol
'gcc2_compiled.' which is supposed to be in section '*DEBUG*'
binutils/objcopy: /home/nickc/st0aiVjO: Invalid operation
Unfortunately it does not address the actual problem of what to do
about symbols in the *DEBUG* section. Maybe you could strip them out
before trying to use objcopy ?
Cheers
