[Bug 1295467] Re: bash crashes when attempting to run a "X!" where X is a single letter

[Brian Murray]

I received a core dump when trying to recreate this bug.  The crash
should result in a .crash file in /var/crash/ and then an apport dialog
offering to file the bug.  It'd be great if you could submit the
automatic crash report for this and then we can mark this bug as a
duplicate of that one. Thanks in advance.

Title:
  bash crashes when attempting to run a "X!" where X is a single letter

Status in “bash” package in Ubuntu:
  Incomplete

Bug description:
  Attempting to run "q!" (yes, I was wrong-window typing vim commands into bash) causes:
  q!: command not found

  malloc: /usr/homes/chet/src/bash/src/parse.y:2314: assertion botched
  realloc: start and end chunk sizes differ
  Aborting...Connection to machinename closed.

  Occurs with any single letter followed by !, or a lone !.  Does not
  occur with ! followed by one or more characters.

  It is not the command-not-found package (removing that was my first
  diagnosis attempt).  I don't really know what else to try.

  It happens on the two Trusty Tahr servers available to me, but not
  Saucy or earlier.
