For completeness, where we discussed the this in relation to gnulib last was:
  https://sourceware.org/ml/libc-alpha/2015-02/threads.html#00181
and drilling down to there is the reference to original crash bug:
  https://sourceware.org/bugzilla/show_bug.cgi?id=4586
That was fixed in 2007 so this must be something else.
