<pre>[WinCairo] Invalid address specified to RtlValidateHeap at std::ctype<char>::_Tidy() when finishing MiniBrowser
trunk@200119, WinCairo port, Debug build
1) Launch MiniBrowser
2) Close the window
3) Invalid address specified to RtlValidateHeap
This issue doesn't happen in every builds.
I think this doesn't happen with a clean build, but a incremental build.
If a build have this issue, this steps reproduces every time.
Log:
