[PATCH] gas/read.c memory leak fix

[Nick Clifton]

Hi Elias,

It's not.  input_scrub_new_file() records the filename in
physical_input_file, and input_file_open records it in file_name.  To
make the patch safe you would have to add xstrdup()s to both of these
and then arrange for the extra memory to be freed at the right time.

Cheers
