This is a false positive in sudo. What's happening is that sudo is taking an error from the program it executed and propagating out to the calling shell. Thus when a called application aborts (i.e. SIGABRT), it also triggers an abort for sudo.

To demonstrate:

  $ sudo sh -c 'echo $$'

results in the following in /var/crash:

  $ ls -l /var/crash/
  total 164
  -rw-r----- 1 root whoopsie 29122 May 30 15:32 _bin_dash.0.crash
  -rw-r----- 1 root whoopsie 133096 May 30 15:32 _usr_bin_sudo.0.crash

Durr, wrong copy-pasta, the actual command is:

  $ sudo sh -c 'kill -ABRT $$'

And in fact this is covered by bug 1565332.
