Webrick dies with illegal instruction 4

Ever since moving to developing a Mac-based RoR, I sometimes see Webrick die just by typing Illegal Instruction 4.

OSX 10.7.2, 10.7.3 and now 10.7.4

ruby 1.9.2p290

rails 3.2.2 and another version starting with 3.1

Until now, it has been pretty harmless, I just pressed the up arrow key, pressed the enter button and restarted the server, and that's all right.

I noticed that immediately after adding a new file to the development environment, this condition is almost always called. But this happened when I recently did not add a new file. But this almost always happens immediately after changing the file. In other words, I don’t think that this ever happened, when I just tested the material, it seems that some modification of the file system is required to run it.

Just now, it happened, but this time, it seems that Webrick somehow wedged in, and after restarting Webrick it would not answer, I had to reboot to clear the condition. Thus, it starts to look less harmless and more like an impending development productivity problem.

Any other Mac developers see this?

Do you have similar problems using non-webrick application servers? I recommend developing with the same application server with which you are deploying, which in this case looks like Passenger.

I ran into this problem after implementing a scope on one of my models

scope :list_only, lambda { show_on_list }

( show_on_list - ).

scope :list_only, where("SomeSQLHere")

( SQL SomeSQLHere), . , , " 4", , , - ?
