Compiling the unibench csv-output testcode with "-mt 2" causes the program to run forever

Extended Description

This was seen on the latest sac2c last week and over the weekend. A testcase heavy in AUD code exists in testsuite/unibench. It was previously working without mt but failed to compile with MT with bug 776. Recently it has started to compile but on Gutemine (Mac OS Leopard) runs forever without using in processor resources. This causes the Masterrun to block.
No strace command exists on the Mac. Does anybody know of a dtrace script that emulates strace so that I can confirm whether or not the program is blocking on a system call?
To reproduce go to sac/testsuite/unibench and run "make checkres MAKE_MT_ALSO=yes".
