             Bug #: 15113
           Summary: sh-elf-ld segfault
           Product: binutils
           Version: 2.24 (HEAD)
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ld
        AssignedTo: address@hidden
        ReportedBy: address@hidden
    Classification: Unclassified


binutils 2.23.51.20130207 configured for sh-elf, host OS X 10.7.5

$ sh-elf-ld a.o b.o crt0.o -o foo.elf
Segmentation fault: 11

The crash happens on line 7264:
  if (htab->srelfuncdesc)
->  BFD_ASSERT (htab->srelfuncdesc->reloc_count * sizeof (Elf32_External_Rela)
        == htab->srelfuncdesc->size);

Running under a debugger, htab->srelfuncdesc contains garbage. When enabling
the Xcode debugger "scribble" option, htab->sfuncdesc, htab->srelfuncdesc and
htab->srofixup all contain the scribble value, suggesting these members have
not been initialized.
