 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.
