Comment (by bgamari):

 Note that I believe `Cabal` strips by default`.

 >  It's hard for me to provide a reproducible example since it is in a
 complex proprietary program and I have of what could be causing this
 besides that increasing the number of capabilities with -N tends to
 increase the frequency of the crashes.

 Quite understandable.  Anything you can offer would be very much
 appreciated. I tested this patch with the testcase from #13615 with over a
 day of runtime without seeing this crash, so it seems that you are
 tickling something odd.
