Well, if anyone would care to compile and run the following program on Mac OS X using pthreads, we can at least tell whether there is a consistent failure:

Here's what it looks it looks like with boost1_31 from fink on OS X 10.3.8: this warning, use -Wno-long-double.)

...not sure if i'm "using pthreads" explicitly, but it all looks good to me. -- Matthew Peltzer -- goochrules@gmail.com
