This makefile causes no problems for me under OpenBSD, running either
version 3.80 or 3.81.  Yes, I ran it many times.  You should have
included the actual operating system that you're using in your bug
report.

You should also check whether you can reproduce this with GNU make
version 3.81, which has been out for over 18 months.

GNU make does not use threads, so this explanation cannot be correct.
