[Bug 1751011] Re: bash crashes in qemu-user environments (bionic)

[Steve Langasek]

<jbicha> slangasek: can you explain the bash 4.4.18-1.1ubuntu1 removal?
<jbicha> because I used sbuild-launchpad-chroot to create an armhf chroot but it is stuck trying to update bash with an error that looks like Debian bug 889869
<slangasek> jbicha: PIE is a security feature, and shouldn't be disabled to work around a bug in qemu-user-static

Title:
  bash crashes in qemu-user environments (bionic)

Status in bash package in Ubuntu:
  Triaged
Status in qemu package in Ubuntu:
  New
Status in bash package in Debian:
  Fix Released

Bug description:
  Attempts to launch bash in an arm64 qemu-user environment in bionic
  results in the following error message:

  bash: xmalloc: .././shell.c:1709: cannot allocate 10 bytes (0 bytes
  allocated)

  This causes any qemu/chroot based bootstrapping to fail as many
  packages invoke bash during postinst.

  Version: bash_4.4.18-1ubuntu1_arm64
  Release: 18.04 pre-release

  QEMU: 2.8.0

  This appears to have been reported and fixed in the corresponding
  Debian package (https://bugs.debian.org/cgi-
  bin/bugreport.cgi?bug=889869)
