             Bug #: 14465
           Summary: GOLD segfaults when linking with discarded .plt
                    sections
           Product: binutils
           Version: 2.23 (HEAD)
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gold
        AssignedTo: address@hidden
        ReportedBy: address@hidden
                CC: address@hidden
    Classification: Unclassified


Discovered whilst creating a test for a different bug:

  % cat discard.t
  SECTIONS
  {
    .text : { *(.text) }
    /DISCARD/ : { *(*) }
  }

  % gold /usr/lib/crt1.o -L/usr/lib/gcc/i686-redhat-linux/4.7.0 -lc -T
discard.t
  Segmentation fault

The problem appears to be that GOLD expects that the .plt and .rel.plt sections
will both be present in the output file.

The test case is obviously nonsensical, but it is a cut down version of a much
larger, and sensible, test case.
