Rails crashes with 'trace trap' error

[natew]

When attempting to run Pygments without the lexer set, I get a trace trap crash with Rails.

zsh: trace trap  rails s

Any of the following will cause the crash:

Pygments.highlight(code)
Pygments.lexer_name_for(code)

This will not crash and works properly:

Pygments.highlight(code, :lexer => 'javascript')

Using this input:

function makeExpandingArea(container) {
  var area = container.querySelector('textarea'),
      span = container.querySelector('span');

 if (area.addEventListener) {
   area.addEventListener('input', function() {
     span.textContent = area.value;
   }, false);
   span.textContent = area.value;
 } else if (area.attachEvent) {
   // IE8 compatibility
   area.attachEvent('onpropertychange', function() {
     span.innerText = area.value;
   });
   span.innerText = area.value;
 }

No one gets this? Can't get it to work on my dev or deploy machines (ubuntu and mac).

And actually the ruby version is 1.9.3-p0 I believe, not sure if thats why.

[jgaskins]

I get this, too, on OS X Lion with Ruby 1.9.3-p125.

I'm porting my blog over to use pygments.rb from Albino. It renders the Ruby example inside it perfectly, but it consistently crashes while attempting to work with the Gherkin example I have.

Here's the code:

class PygmentsHTML < Redcarpet::Render::HTML
   def block_code(code, language)
     Pygments.highlight(code, lexer: language)
   end
end

I verified that the code and language arguments are passed in properly and Pygments is working fine in irb, but it's having trouble from within Rails.

Same problem here

I see this issue, also on a Lion/Mac system (but not Ubuntu). To reproduce, on 1.9.3p125: simply get the gollum gem and run it against your github wiki which has a page that performs syntax highlighting. It will blow up after that - so any Mac user using gollum (which is great for editing github pages) is going to run into this if they do syntax highlighting.

Also check out this related link which I think could be explaining the cause for Mac crashes: https://github.com/gitlabhq/gitlabhq/pull/245

[jamesduncombe]

Getting the same problem here on OSX 10.6.8, ruby-1.9.3-p125, pygments.rb v0.2.13.

It seems to work fine on my other Mac which is running OSX Lion.

This is fixed since 0.3.0.
