--- Comment #4 from Andrew Macleod <amacleod at redhat dot com> --- I'm also having difficulty reproducing. The SPEC 2006 I have access to doesn't seem to want to work with a modern perl. I also don't have zen4 or zen5, I was going to see if it reproduced on vanilla x86-64. Any reduction/reproducers would be very helpful...
