            Bug ID: 26918
           Summary: s390x: ld segfaults when htab->elf.sgot is NULL
           Product: binutils
           Version: 2.32
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: ld
          Assignee: unassigned at sourceware dot org
          Reporter: iii at linux dot ibm.com
  Target Milestone: ---

The following (arguably pointless) code crashes ld on s390x:

$ cat test.c
int add (int a, int b) { return a + b; }

$ cat test.lds
SECTIONS { /DISCARD/ : { *(*) } }

$ gcc -nostartfiles -Wl,--script=test.lds test.c
collect2: fatal error: ld terminated with signal 11 [Segmentation fault], core
dumped
compilation terminated.

Thread 3.1 "ld" received signal SIGSEGV, Segmentation fault.
