Issue #7119 has been updated by mame (Yusuke Endoh).

Status changed from Open to Third Party's Issue
Assignee set to mame (Yusuke Endoh)

(Hooray, wisp user!)

The trace strongly suggests an eventmachine issue:

> 6   libSystem.B.dylib             	0x00007fff85b5e1ba _sigtramp + 26
> 7   rubyeventmachine.bundle       	0x000000010079a171 t_set_comm_inactivity_timeout(unsigned long, unsigned long, unsigned long) + 11 (rubymain.cpp:392)

So, could you contact on eventmachine developers?
Incidentally, it worked with trunk on Linux.


> On other versions of Ruby, the script didn't work in the expected manner

This looks another issue due to wisp.  Did you use Google Chrome or Firefox?
If I had a chance, I would test it on os x.  (I have no Mac.)

Running Wisp causes a segmentation fault.

Wisp is only version 0.1.0, but its code is too simple for it itself to cause a segmentation fault.

    ruby 2.0.0dev (2012-09-28 trunk 37049) [x86_64-darwin10.8.0]

On other versions of Ruby, the script didn't work in the expected manner (a web page was generated, but the page didn't show any lines of code being lit up by wisps), but it did not segfault.

Attached is OSX's crash file.
