Title:
  [Ubuntu 17.04] 'make test' failures seen when e2fsprogs instrumented
  with 'undefined behavior sanitizer'

Status in The Ubuntu-power-systems project:
  New
Status in e2fsprogs package in Ubuntu:
  New

Bug description:
  ---Problem Description---
  'make test' shows '262 tests failed' when e2fsprogs instrumented with 'Undefined Behavior Sanitizer' 

  Contact Information = nasastry at in.ibm.com 

  ---uname output---
  Linux powerkvm1-lp1 4.10.0-9-generic #11-Ubuntu SMP Mon Feb 20 13:45:11 UTC 2017 ppc64le ppc64le ppc64le GNU/Linux

  Machine Type = 8284-22A 

  ---Debugger---
  A debugger is not configured

  ---Steps to Reproduce---
   1. Prepare the build environment and download e2fsprogs
  apt-get build-dep -y e2fsprogs
  mkdir pkg
  cd pkg
  apt-get source e2fsprogs
  cd e2fsprogs-1.43.4/

  2. Now instrument with 'undefined behavior sanitizer' and run 'make test'
  dh_testdir
  dh_auto_configure -- CFLAGS="-fsanitize=undefined -fsanitize=address" LDFLAGS="-fsanitize=undefined -fsanitize=address" CXXFLAGS="-fsanitize=undefined -fsanitize=address"
  dh_auto_build
  dh_auto_test
