           Summary: strip crashes when it does not recognise the file
                    format
           Product: binutils
           Version: 2.21
            Status: NEW

          Priority: P2
         Component: binutils

The crash occurs when the target is of an unknown format.
The problem seems to be a NULL-pointer dereference in ./bfd/bfdio.c on line 206
as can be seen from the gdb output below:

/usr/bin/strip:libeay32.lib(tmp32/e_capi.obj): Unable to recognize the format
of file: File format not recognized

Program received signal SIGSEGV, Segmentation fault.
