Chris Provenzano's beta pthread package based on POSIX1003.4a Draft
8 with a few minor patches compiles and almost runs through its
tests on FreeBSD 2.05B. The test that fails is the
floating point preemption test, which dies with a:
> pid 4510 (test_preemption_) exited with masked floating point exceptions 0x41
I'll bet bde can suggest a fix for this; I recall him commenting on
floating point in signal handlers.
I coincidentally had decided to check pthreads out this morning to
see if it could go on the experimental section of the CD-ROM.
Jordan: Do you want this like this on the CD-ROM?
It is certainly ready for hacker use. The patches I applied to
sipb.mit.edu:/pub/pthreads/pthreads-1_60_beta2.tar.gz were:
