From: Aaron Patterson Date: 2010-02-03T10:42:20+09:00 Subject: [ruby-core:28022] [Bug #948](Closed) dl: cannot pass double value correctly on all x86_64 systems Issue #948 has been updated by Aaron Patterson. Status changed from Assigned to Closed ruby -v set to ruby 1.9.2dev (2010-02-03 trunk 26544) [x86_64-darwin10.2.0] DL now uses libffi for function calling. Steer clear of using CFunc#call. Use Function#call instead, and you will use libffi which will deal with x86_64 systems. ---------------------------------------- http://redmine.ruby-lang.org/issues/show/948 ---------------------------------------- http://redmine.ruby-lang.org
