[naruse (Yui NARUSE)]

It seems in garbage collection; marking or freeing some invalid objet causes segv.
But the murderer is not clear.

[corneverbruggen (Corné Verbruggen)]

Running rails 3.1.0.rc4 on ruby 1.9.2 on Ubuntu 11.04 64bit, I get segfaults that might point at the same problem. It happens randomly when starting the app. The line at the top of the ouput which ends with "[BUG] Segmentation fault" shows different source files and line numbers on each run.

Every now and then during unit testing I also got "*** glibc detected *** ruby: double free or corruption (fasttop)" errors. After searching around I found a question on Stackoverflow (http://stackoverflow.com/questions/2235355/ruby-glibc-coredump-double-free-or-corruption) with an answer that suggested to do set MALLOC_CHECK_ to 2 with "export MALLOC_CHECK_=2". I don't know much about glibc and segfaults, but whenever I set MALLOC_CHECK_ to 2, the segfaults don't happen anymore. No guarantee of course, because the error happens randomly, but after many trials I get the impression that segfaults don't happen after this setting.

Here is one of the segfault outputs:

Issue #4821 has been updated by Corné Verbruggen.

Running rails 3.1.0.rc4 on ruby 1.9.2 on Ubuntu 11.04 64bit, I get segfaults that might point at the same problem. It happens randomly when starting the app. The line at the top of the ouput which ends with "[BUG] Segmentation fault" shows different source files and line numbers on each run.

Every now and then during unit testing I also got "*** glibc detected *** ruby: double free or corruption (fasttop)" errors. After searching around I found a question on Stackoverflow (http://stackoverflow.com/questions/2235355/ruby-glibc-coredump-double-free-or-corruption) with an answer that suggested to do set MALLOC_CHECK_ to 2 with "export MALLOC_CHECK_=2". I don't know much about glibc and segfaults, but whenever I set MALLOC_CHECK_ to 2, the segfaults don't happen anymore. No guarantee of course, because the error happens randomly, but after many trials I get the impression that segfaults don't happen after this setting.

Hi Corné,

Would it be possible to put your application somewhere? I can take a
look and try to reduce the problem case.

Hi Aaron,

thanks! I sent you an email with a url.

It looks like I have the same (or very similar issue) in Rails 3.1.0.rc1-4.
I was trying to run request specs using Capybara from source and sprockets.

Attaching the Gemfile.lock with all the dependencies used and the terminal output.

[dnagir (Dmytrii Nagirniak)]

It seems the problem is related to the therubyracer gem. If I remove it, no errors occur. I'll lodge bug there. Would be nice if it could be confirmed.

[cowboyd (Charles Lowell)]

As of 0.9.0, therubyracer does not support multithreaded webservers. We're working on this, but in the meantime, there are some workarounds here:

[cowboyd (Charles Lowell)]

I've written up the issue here to explain what's going on, and timing for a comprehensive fix.

http://blog.thefrontside.net/2011/06/13/therubyracer-isnt-threadsafe-yet/

[corneverbruggen (Corné Verbruggen)]

This does not seem to be the bug that I experience, because I don't use therubyracer. I thought it might be a similar bug in execjs, but even disabling the uglifier gem (so not using execjs anymore) does not solve the bug.

[Falcon (Ilya Sokolov)]

We don't use "therubyracer". Bug in something like webrick. Because we switch webrick to unicorn server, and all works great.

[corneverbruggen (Corné Verbruggen)]

I also get the segfault when running "rails generate" and when running tests. So it does not seem to be solely a problem with webrick? Maybe the causes are multiple?

[corneverbruggen (Corné Verbruggen)]

Did some further tests to find out where this (for me) hard to understand segfaults came from. I still don't know the root cause, but now I do know that using devise together with meta_search (1.1.0.pre) resulted in the segfaults. Disabling either one of the two "solved" the problem.

I will create an issue at the meta_search project page and investigate this further, but am still wondering whether this isn't a bug (i.e. Segmentation Faults) in Ruby in the end?

I also got segfaults on OSX 10.6 on mongrel and unicorn after updating the Gems sass, compass and adding a file splitter that reads in and writes a few files. - and the segfaults only came in requests where this file processing is done.

I've tried, but I can't seem to reproduce this. Christian, are you still seeing these issues? If so, could you post an application that reproduces the problem? I'm happy to do this off-list if it's more convenient.

I'm closing this since I haven't heard any feedback from the reporter. If you can post an isolated example, I would be happy to help out.

Thanks!
