intermittent abort crash from make TEST=hs_try_putmvar003 WAY=threaded2

in a bash shell type

for i in {1..10}; do make TEST=hs_try_putmvar003 WAY=threaded2 ; done

if you look at the output you will probably see at least one instance of

cd "./concurrent/should_run/hs_try_putmvar003.run" && ./hs_try_putmvar003 +RTS -N2 -ls -RTS 1 16 32 100
Wrong exit code for hs_try_putmvar003(threaded2)(expected 0 , actual 134 )
Stderr ( hs_try_putmvar003 ):
/bin/sh: line 1: 45386 Abort trap: 6           ./hs_try_putmvar003 +RTS -N2 -ls -RTS 1 16 32 100
*** unexpected failure for hs_try_putmvar003(threaded2)

This was on a Mac running the latest OS and Xcode. I can attach the Apple problem report if that helps.
