I have the following output at the end of rspec with https://github.com/wpscanteam/wpscan :

Thanks for reporting! Will look into it.

deanmarano · 2013-03-12T16:06:30Z

I'm seeing this issue as well - any ideas as to what it could be?

hanshasselberg · 2013-03-12T16:07:19Z

@deanmarano How can I reproduce it?

erwanlr · 2013-03-12T16:10:05Z

(If you want a smaller piece of code, this one https://gist.github.com/erwanlr/5099652 also have the issue)

dwaynemac · 2013-04-06T16:18:39Z

i'm having this problem too.

dwaynemac · 2013-04-08T00:59:02Z

has anyone found some work around at least? I can't even run rake tasks :(

erwanlr · 2013-04-09T16:14:25Z

With the master version, the error is the same but from a different gem :o

Any fix or workaround for this? I get this error when using typhoeus with delayed_job
Here is my mega-long stack trace https://gist.github.com/jonesdeini/360b17b95afaadea7d3c

hanshasselberg · 2013-05-12T21:22:34Z

I'll have some time at the end of the week and I'm going to fix some bugs! Will see how hard that one is...

jonesdeini · 2013-05-13T01:46:04Z

Let me know if you need any more information or if there is anything I can do to help. Typhoeus is such a cool project and I would love to help out if possible. Thank you for all your hard work!

hanshasselberg · 2013-05-13T07:51:33Z

@jonesdeini Thanks for the kind words! Any help is highly appreciated! You could for example go ahead and fix bugs. Some of them are less complex like typhoeus/typhoeus#233 or #32. I you would like to do something else thats cool too. Just email me if you need a pointer if you run into a problem or have question!

hanshasselberg · 2013-05-16T22:10:44Z

@erwanlr @dwaynemac @jonesdeini could somebody provide code to reproduce your issue? wpscan test suite works for me and the gist doesn't raise anything. Tested with Typhoeus 0.6.3 and Ethon 0.5.11.

erwanlr · 2013-05-17T13:53:41Z

What version of ruby are you using ?

I've retested the gist (https://gist.github.com/erwanlr/5099652, spec_helper.rb & test_spec.rb have to be moved in a spec directory, then you run rspec), and ruby 1.9.3p194 & 1.9.3p362

Like I said 1 month ago, the error is the same but from a different gem :

i'll try to look into it. We've downgraded to Typhoeus 0.5.0.alpha and are with this version because we have some deadlines right now. As soon as I can I'll retest this.

Humm, I'm using curl 7.29, and in the 7.30 changelog I saw this : http://sourceforge.net/p/curl/bugs/1194/ (from http://curl.haxx.se/changes.html#7_30_0)

I will update curl to the 7.30 and retry tomorrow

hanshasselberg · 2013-05-17T20:26:00Z

Very good catch!

jonesdeini · 2013-05-18T02:10:12Z

I upgraded curl to 7.30 and still have the same error.

It appears my example will be dependant on Rails since delayed_job depends on ActiveRecord.
Hopefully I will be able to extract an example which does not depend on Rails.

erwanlr · 2013-05-18T07:59:41Z

Works for me

linrock · 2013-07-28T04:48:36Z

I ran rspec against curl versions 7.28.1, 7.29.0, 7.30.0, and 7.31.0. Only 7.29.0 segfaults (in multi_cleanup). Must be because of the bug linked by @erwanlr.

hanshasselberg · 2013-07-28T08:41:12Z

thanks @linrock. I'm going to close this issue then. Happy to reopen when necessary.

AndreasSoiron · 2013-10-30T18:37:07Z

I got problems with curl 7.30.0 in OS X 10.9. Updating to curl 7.33 fixed it for me.

hanshasselberg · 2013-10-30T20:18:38Z

@AndreasSoiron thanks for reporting!
