  Hum, I haven't compiled with thread in a long time... But I remember
Igor made some patches to unify Windows/Unix threading recently, that may
be the cause of the problem.

   Igor ???

   Just rebuilt with --with-threads on linux Red Hat 8.0, it compiles fine
the general tests pass normally but not the thread one:

paphio:~/XML -> ./testThreads
Segmentation fault

Running under gdb , I see a bunch of threads being created ...
[New Thread 2064637 (LWP 1319)]
[New Thread 2072830 (LWP 1320)]
[New Thread 2081023 (LWP 1321)]
pthread_create: Interrupted system call

Program exited with code 01.
(gdb)

   hum, that doesn't help :-(

strace ends up the following way:

--- SIGRTMIN (Real-time signal 0) ---
<... rt_sigsuspend resumed> )           = -1 EINTR (Interrupted system call)
sigreturn()                             = ? (mask now [RTMIN])
write(4, "\2000\3 \1\0\0\0\2\0X\1\2000\3@\2000\3 \0\0\0\0\0\0\0\0"..., 148) = 148
rt_sigprocmask(SIG_SETMASK, NULL, [RTMIN], 8) = 0
rt_sigsuspend([] <unfinished ...>

paphio:~/XML ->

   not much better :-\
