• Status: Closed
• Assignee: naruse (Yui NARUSE)
• Target version: 2.0.0
• ruby -v: ruby 1.9.3dev (2010-05-27 trunk 28040) [i386-mswin32_90]

=begin
Ruby-trunk (r28040) compiles fine with VS2008 but when it starts generating RDoc documentation it crashes with a stack overflow:

(...)
Generating RDoc documentation
.\ruby.exe -I./lib -I".ext/i386-mswin32_90" "./tool/runruby.rb" --extout=".ext" -- "./bin/rdoc" --no-force-update --all --ri --op ".ext/rdoc" "."
NMAKE : fatal error U1077: '.\ruby.exe' : return code '0xc00000fd'
Stop.

More information from the application log:

Faulting application ruby.exe, version 1.9.3.0, time stamp 0x4bfe8abc, faulting module ntdll.dll, version 6.0.6002.18005, time stamp 0x49e03821, exception code 0xc00000fd, fault offset 0x00066578, process id 0x33c, application start time 0x01cafdb25d481203.

Ruby-1.9.2 (ruby 1.9.2dev (2010-05-27 revision 28042) [i386-mswin32_90]) exhibits exactly the same problem.

succeeded to reproduce.

memo:

ruby crashes in ruby_xrealloc() because ptr is invalid.
objspace = 0

Oh, this is the well known problem (by especially Naruse and me)
