Bug #5170: Date.strptime Segmentation Fault

• Status: Closed
• Assignee: tadf (tadayoshi funaba)
• Target version: 1.9.3
• ruby -v: ruby 1.8.7 (2010-12-23 patchlevel 330) [i386-mingw32]

[cfis (Charlie Savage)]

require 'date'
Date.strptime('01-31-2011', '%m/%d/%Y')

This happens on Mingw:

ruby 1.9.3dev (2011-07-28 revision 32716) [i386-mingw32]

It also happens on Linux:

ruby 1.9.3dev (2011-07-31 revision 32789) [x86_64-linux]

This is pretty high priority for us because we need to now use Date.strptime since Date.parse no longer handles US style dates correctly.

• File 0001-ext-date-date_core.c-d_new_by_frags-raise-on-non-Has.patch 0001-ext-date-date_core.c-d_new_by_frags-raise-on-non-Has.patch added

I can reproduce this on trunk with x86_64, too. The attached patch should fix it.

For git users against trunk (trivial cherry-pick applies to the 1.9.3 branch, too):
