Thread issues with ruby 1.8.0 on OpenBSD 3.3

I’m seeing problems with threading using ruby 1.8.0 on OpenBSD 3.3.

When I use threads, I get

longjump botch.
Illegal instruction (core dumped)

Following is a short script that reproduces the problem.
This script runs fine using ruby 1.8.0 on Solaris 8.

Are there known issues with ruby threading on OpenBSD?

Thanks,
Rick

require 'thread’
threads = []
q = Queue.new
threads << Thread.new { puts q.pop }
q.push(“gronk”)
threads.each { |t| t.join }

Can you give a stack trace ?

Run your script under gdb and when it crash use the command `bt'

Guy,

Here is the gdb session after the crash:

(gdb) bt
#0 0x8f29ae8 in _longjmp ()
#1 0x8f29aec in _longjmp ()
#2 0x7 in ?? ()
(gdb) quit

This is on a Sparc 5 which I didn’t mention earlier.

Perhaps best to see on a OpenBSD mailing list : there were well know
problems with Alpha for longjmp

I don't know for sparc

I don’t think that it’s a sparc issue since the same code runs fine
under Solaris. I have several other architecture/OS combinations
available that work fine as well. It is probably related to OpenBSD.

I’ll dig into it further this afternoon.

Thanks for your thoughts.

I'm agree with you

moulon% ruby -v
ruby 1.8.0 (2003-08-04) [sparc-solaris2.7]

This is why I've said
