This was against 0.8.1 nginx lua module tag, I should add

[agentzh]

I had not run ngx_lua's test suite against nginx 1.4.1 and it's been working with 1.2.x. I just tried running the test suite against 1.4.1 and the tests for setting request cookies are indeed failing (and also crashing) with exactly the same backtraces you've shown. I'll try to find a fix for it. Thank you for the report :)

[agentzh]

Just fixed in git master HEAD. Please try it out :)

[rfwatson]

Thank you! I will test in the morning and let you know if successful.
