Hello,<br>
<br>
Before starting, this is my first bug report here, feel free to tell me if =
I need to add/modify anything.<br>
<br>
I came across a weird segmentation fault, and I apologies for not being abl=
e to be more precise about what is happening.<br>
Although I have a how-to-reproduce, the error happens at random points in e=
ither rails or gems.<br>
I have several RoR applications, and this one is the only having this probl=
em.<br>
<br>
Environment : MacOS, see ruby -v, rvm (stable) and I attached my Gemfile.lo=
ck and CrashReporter.<br>
<br>
How to reproduce :<br>
1. rails s<br>
2. Open localhost:3000 in browser (is OK)<br>
3. Reload<br>
<br>
You get the segmentation fault. Always the same : first loading is correct,=
 then the second fails (even if I restart rails in between).<br>
<br>
It is not on one component, nonetheless I have the same filenames if I try =
again (line of code between parenthesis) :<br>
* gems/dalli-2.3.0/lib/dalli/socket.rb:31 (value &lt;&lt; kgio_read!(count =
- value.bytesize))<br>
* gems/activesupport-3.2.13/lib/active_support/core_ext/hash/except.rb:15 (=
dup.except!(*keys))<br>
* gems/actionpack-3.2.13/lib/action_view/renderer/renderer.rb:51 (@_partial=
_renderer ||=3D PartialRenderer.new(@lookup_context))<br>
* gems/activesupport-3.2.13/lib/active_support/core_ext/module/remove_metho=
d.rb:4 (remove_method(method))<br>
* code/local/app/helpers/cms_helper.rb:152 (prev_char_ind =3D paragraph[0..=
prev_char_ind].rindex(&quot; &quot;) - 1)<br>
* gems/haml-3.1.4/lib/haml/filters.rb:214 (#{text.rstrip.gsub(&quot;\n&quot=
;, &quot;\n =A0 =A0&quot;)})<br>
* gems/rack-mini-profiler-0.1.23/Ruby/lib/mini_profiler/sql_timer_struct.rb=
:15 (Kernel.caller.each do |ln|)<br>
<br>
As you can see, I can&#39;t isolate some sort of &quot;pattern&quot;.<br>
