Bug #3600: HP-UX compilation
http://redmine.ruby-lang.org/issues/show/3600

Author: Graham Agnew
Status: Open, Priority: Normal
Target version: 1.9.1 RC2
ruby -v: ruby 1.9.2dev (2010-07-11 revision 28618) [ia64-hpux11.23]

Hi,

I've had reasonable success with compiling 1.9.1 on HP-UX.  But 1.9.2 has been problematic since preview3 came out.  It seems the main issue is with threads.  A very simple example (as follows) works fine on 1.9.1 but the thread never seems to start on 1.9.2-rc2.

<code>
thr = Thread.new { puts "thr start"; sleep 1; puts "thr exit" }
puts "main join"
thr.join
puts "main exit"
</code>

Sometimes it blocks indefinitely, and when I press control-C to stop it, I get a bus error:

<trace>
try_thread.rb: [BUG] Bus Error

[NOTE]
You may have encountered a bug in the Ruby interpreter or extension libraries.
Bug reports are welcome.

Abort(coredump)

Some other times I get a seg-fault.  Can anyone point me to changes to threading in 1.9.2 so that I can investigate this more quickly and maybe find a solution?

Thanks,
Graham.
