Bug #8756

SEGFAULT caused by `p Struct.new(:q?).instance_methods`

Added by misfo (Trent Ogren) over 10 years ago. Updated about 10 years ago.

Status:
Closed
Target version:
-
ruby -v:
ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-darwin12.4.0]
[ruby-core:<unknown>]

Description

Printing the instance methods for a Struct with a member name ending in a question mark causes a seg fault. I've confirmed this using the 2.0.0p247 on OS X and linux.

Here's the minimal test case for reproducing from a shell:

$ ruby -e 'p Struct.new(:q?).instance_methods'
-e:1: [BUG] Segmentation fault
ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-darwin12.4.0]
