            Bug ID: 18687
           Summary: GNU as segfaults when file ended by '.endr' or '.endm'
                    directive with spaces and end of line
           Product: binutils
           Version: 2.24
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gas

Sample source code for that GNU as segfaults.

For following code the GNU as segfaults:

        .macro Xv
        .string "\Xv"
        .endm      << end of line

this code have only three lines, where last line is not ended by newline.

GNU as prints messages:
irptest.s: Assembler messages:
irptest.s:3: Warning: partial line at end of file ignored
irptest.s:1: Error: unexpected end of file in macro `xv' definition

and segfaults.

This same problem has been encountered for that code:

        .irp Xv, aaaa
        .string "\Xv"
        .endr   << end of line

Likewise, that code have line that is not ended by newline.
