Thanks Marcus, I had spotted that failure, but didn't know what to do about 
it.  The fact that it's specific to gcc on that one specific platform is 
particulary frustrating!

I have to be honest: I'm not even sure how to go about debugging this: 
basically the test program spawns 10 threads each of which then runs the 
regex test code.  In other words it's a stress-test to detect 
multi-threading issues.  Are there any known problems with gcc and threading 
on that platform?

Failing that, if you can run it under gdb and see what traps that might 
suggest something.

And finally, is gcc on tru64 available on the HP testdrive machines?  I had 
a quick look last week, but couldn't see anything?

Many thanks, John.
