Bug #5211: Segmentation fault in Enumerator#each

• Status: Rejected
• Assignee: mrkn (Kenta Murata)
• Target version: 1.9.2
• ruby -v: ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-darwin11.1.0]

[woollyams (Mike Williams)]

Under ruby-1.9.2-p290, on OS X Lion, the following code

@e1 = %w(strike strike strike).to_enum
@e2 = [1,2,3].to_enum

p [@e1.next, @e2.next]
p [@e1.next, @e2.next]
p [@e1.next, @e2.next]

Fails with a Segmentation fault.

Same code works fine in both ruby-1.9.2-p180 and ruby-1.9.3dev.

On 1.9.3, I cannot reproduce this issue using gcc-4.2 with -O3 and llvm-gcc with -O0 on OS X 10.7 (Lion).
Which version of gcc do you use to compile ruby?
llvm-gcc and clang with -On (n>0) are not supported to build 1.9.3.

On the other hand, the present ruby_1_9_2 branch doesn't support Lion. Backporting #5074 is able to resolve this.
llvm-gcc and clang are still not supported to build 1.9.2 even if #5074 were to be backported.

Please use gcc-4.2 for building 1.9.2 and 1.9.3.
