New issue 404 by [email protected]: Crash in mksnapshot on Mac http://code.google.com/p/v8/issues/detail?id=404 Steps: 1. Checkout Chromium 20723 2. In src/DEPS change v8 dependency to point to "http://v8.googlecode.com/svn/branches/bleeding_e...@2468"; and sync again. 3. cd into src/v8/tools/gyp 4. Run xcodebuild -configuration Release -project v8.xcodeproj - bonjourbuildhosts -target v8_snapshot and observe it fail. 4.1. You can cd into src/xcodebuild/Release and run ./mksnapshot test.cc to observe the crash. dhcp-172-28-174-146:~/chrome/src/xcodebuild/Release yurys$ gdb -- args ./mksnapshot ss.cc GNU gdb 6.3.50-20050815 (Apple version gdb-962) (Sat Jul 26 08:14:40 UTC 2008) Copyright 2004 Free Software Foundation, Inc.
