[Bug binutils/32467] nm write memory caught segmentation fault

--- Comment #1 from Nick Clifton <nickc at redhat dot com> ---
The problem is the one of the symbols contains an @ character:

 
_ZN1@SerialFOTBuilder12endExtensionERKN10FOTBuilder24CompoundExtensionFlowObjE

Because nm is being run with the --without-symbol-versions option it is
(temporarily) trying to replace the @ character with a NUL.  But since the
symbol table has been mmap()ed from the file it is in read-only memory, and so
a write fault occurs.

I have a local patch to fix this which I am testing now.
