Bug #5090
closedSegfault using Enumerator
Description
Running bug_report.rb on my laptop simply raises a StopIteration as expected, but running it on a compute cluster node (Intel Xeon 2.93 GHz - Nehalem series) generates a segfault (below, and in "gcc and output.txt" when getting the next element from an Enumerator.
Ruby was compiled as described in configure.log and make.log
$ ruby bug_report.rb bug_report.rb bug_report.rb
bug_report.rb:6: [BUG] Segmentation fault
