            Bug ID: 22537
           Summary: Segmentation fault with static PIE
           Product: binutils
           Version: 2.30 (HEAD)
            Status: NEW
          Severity: normal
          Priority: P2

          Reporter: hjl.tools at gmail dot com
  Target Milestone: ---
            Target: hppa-linux

On hjl/pie/static branch in glibc git repo, when --enable-static-pie
is used to configure glibc, I got
