• Component: New Bugs
• Status: RESOLVED FIXED

[Fujii Hironori]

This patch changed to use Debug CRT for Windows Debug build.
https://github.com/WebKit/WebKit/commit/f60c50cc4705a69df96dcd29e47d2ea4927b6d5e

With the patch, Windows Debug build MiniBrowser crashes soon just by browsing some web pages.
