Bug #2330: Non systematic segmentation fault with autoload rubyspec
http://redmine.ruby-lang.org/issues/show/2330

Author: Marc-Andre Lafortune
Status: Open, Priority: Urgent
Assigned to: Yukihiro Matsumoto, Category: core, Target version: 1.9.2
ruby -v: ruby 1.9.2dev (2009-11-04 trunk 25641) [x86_64-darwin10.0.0]

Starting from r25601, the following rubyspec will crash about half of the time (just repeat a couple of times):

$ mspec -t rubydev core/kernel/autoload_spec.rb

Issue #2330 has been updated by Marc-Andre Lafortune.

Priority changed from Urgent to High

Can't reproduce on PowerBook with Leopard, nor on a MacBook Pro with Leopard.

On my Mac Pro with Snow Leopard, though, it's pretty systematic. I rebuilt the nightly download from scratch and got the same crash  Maybe a strange 64 bit issue?

I'll try tomorrow on a different machine with Snow Leopard.

Issue #2330 has been updated by Marc-Andre Lafortune.


Reproduced on a MacBook Pro (thus a different processor) running Snow Leopard, same error.

Is there a compile option I can use to compile ruby in 32 bit instead of 64?
