• Status: Closed

Tested on 1.9.2-head, 1.9.2-p0 and 1.9.2-p180.

If I run this:

ruby -e '(0..255).zip(0..255)'


I get this:

-e:1: [BUG] Segmentation fault

[2]    16898 abort      ruby -e '(0..255).zip(0..255)'

But if I do:

ruby -e '((0..255).to_a).zip(0..255)'

it works ok.

We haven't try the Lion beta release, but We've try the Lion production release.
(yeah, the Lion has been released yesterday)

And I'd report we confirmed your testcase work for me on Lion production release.
Can you please try latest Lion release?

Thanks.

Applying r32201 fixes this issue too.
