[Bug 1689344] Re: print of __glib_assert_msg not returning a message

[Launchpad Bug Tracker]

This bug was fixed in the package apport - 2.20.4-0ubuntu4.1

---------------
apport (2.20.4-0ubuntu4.1) zesty; urgency=medium

  * Disable report.test_add_gdb_info_abort_glib test case for now, as the
    glib assertion message is broken under current Ubuntu (LP: #1689344)
  * Resolve autopkgtest failures in test_backend_apt_dpkg.py due to issues
    with apt key ring. Thanks to Dimitri John Ledkov for the patch.
    (LP: #1651623)

Bug description:
  [Impact]
  apport's test, test_add_gdb_info_abort_glib is failing due to a change somewhere in glib2.0, how its built, or gdb. The test shall be disabled while the matter is investigated.

  [Test Case]
  Run the autopkgtest and observe the failure.
  With the version of the package in proposed the test will not be run.

  [Regression Potential]
  We are just disabling a broken test so there is none.

  apport's test test_add_gdb_info_abort_glib has been failing for a bit,
  since zesty(?), now. Digging into this matter I discovered that using
  gdb to "print __glib_assert_msg" is resulting in different behavior.

  With the generated binary, it used to return the following:

  $2 = 0x7fadc0 "ERROR:<stdin>:2:main: assertion failed (1 < 0): (1 <
  0)"

  However, now I am seeing:

  (gdb) print __glib_assert_msg
  $1 = 1332592064
  (gdb) print (char*) __glib_assert_msg
  $2 = 0x4f6dbdc0 <error: Cannot access memory at address 0x4f6dbdc0>

  This seems to be a regression in gdb itself, I've added an apport task
  though to track the disabling of the autopkgtest which utilizes this
  command.
