Subject: Thread Problems - Random Segfaults


I have a thread-intensive application that gives random segfaults. They occur at
random places in both my own code and third party code.

 ./dhcp.rb:34: [BUG] Segmentation fault
 /sw/lib/ruby/site_ruby/1.6/http-access2.rb:676: [BUG] Segmentation fault
 /sw/lib/ruby/site_ruby/1.6/nqxml/entities.rb:18: [BUG] Segmentation fault

My code is not very special, it is mostly threads that sleep and wake up to do
a SOAP call or a DRb call. All shared data is protected with a mutex.

Are threads known to be buggy?

My platform is OS X 10.2.6 with Ruby 1.6.7:

 ruby 1.6.7 (2002-03-01) [powerpc-darwin6.6]
