glibc in redhat 7.0/7.1 has broken posix threads

[Robert Hyatt]

I have been running "crafty" for years... on SMP machines, using redhat
5.* and 6.* releases with no problems.  I have tried both 7.0 and 7.1 and
posix threads seems to be broken.

You can download crafty from ftp.cis.uab.edu/pub/hyatt/v18/crafty-18.10.tar.gz
and untar it.  Then type "make".  To run it, type the following:

crafty
mt=4
move

it will hang.  The debugger says that the first thing forked by glibc
(control thread) has crashed with a segv error.  It will fail every
time.  And it will work every time on 6.2 and earlier versions.  A code
compiled on 6.2 will not work on 7.0 or 7.1 either, yet if I install a
2.4 kernel on my 6.2 box, it works fine since I am still using the old
glibc library.

Something is obviously broken badly, and has been broken badly for several
months.

Any suggestions?  Or do you need any more information???  Or have a
work-around?
