--- Comment #3 from Fujii Hironori <Hironori.Fujii at sony.com> ---
A DLL ucrtbased.dll is observed in the call stack of comment 0.
According to a following document, ucrtbased.dll is just for dynamically linked CRT.

  CRT Library Features

This is strange because WebKit is compiled with /MT switch to use static CRT.
By using "dumpbin /imports WebKit.dll", it can be observed that vcruntime140d.dll and ucrtbased.dll are linked.

In Source/WebKit/PlatformWin.cmake:

> else ()
> endif ()

LIBCMT and LIBCMTD are ignored for WinCairo port.
But, they are the static CRT.
This code have been introduced in Bug 147851.
