segfaults in production with 0.10.2

[sasa555]

Hello,

we have been using therubyracer 0.7.5 for more than a year in the production. This has been working flawlessly under heavy load. 

Yesterday, we upgraded to version 0.10.2. The gem still works, but after some time, segmentation fault occurs:

bundle/ruby/1.9.1/gems/therubyracer-0.10.1/lib/v8/portal/proxies.rb:145: [BUG] Segmentation fault

ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]

Once we reverted back to 0.7.5 the segfaults stopped occurring.

The server is ran on the Ubuntu 12.04, and hosted behind Apache / Phusion Passenger combo.

Any suggestions?

Best regards,

Sasha,

010.x has some fundamental flaws with the way it manages memory that have been addressed on master (0.11.x)

I would try using one of the pre-releases and see if this solves your problem for you.

cheers,

Charles

Thank you!

I'll wait till the release comes out and give it a try.
