[Bug 1838014] Re: random segfaults in gawk on ppc64el xenial, gawk 1:4.1.3+dfsg-0.1

[Colin Ian King]

Seeing segfaults in grep too:

checking dependency style of gcc... ./configure: line 3918: 25741 Segmentation fault      (core dumped) grep sub/conftst1.h sub/conftest.Po > /dev/null 2>&1
./configure: line 3918: 25779 Segmentation fault      (core dumped) grep sub/conftst1.h sub/conftest.Po > /dev/null 2>&1

Bug description:
  When building fwts 19.07.00 in a VM or a chroot on Xenial ppc64el, I'm
  seeing segfaults in awk:

  ./configure: line 10171: 15840 Done                    $LD --help 2>&1
       15842 Segmentation fault      (core dumped) | $EGREP ': supported targets:.* elf' > /dev/null

  awk: cmd. line:1: (FILENAME=- FNR=1) fatal error: internal error:
  segfault

  I've also seen segfaults in grep, so I think this may be a recent
  dependency change.
