<pre>A DLL ucrtbased.dll is observed in the call stack of <a href="show_bug.cgi?id=157067#c0">comment 0</a>.
According to a following document, ucrtbased.dll is just for dynamically linked CRT.
CRT Library Features
<a href="https://msdn.microsoft.com/en-us/library/abx4dbyh.aspx">https://msdn.microsoft.com/en-us/library/abx4dbyh.aspx</a>
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:
<span class="quote">> if (${WTF_PLATFORM_WIN_CAIRO})
> set(CMAKE_SHARED_LINKER_FLAGS "${CMAKE_SHARED_LINKER_FLAGS} /NODEFAULTLIB:LIBCMT /NODEFAULTLIB:LIBCMTD")
> else ()
> set(CMAKE_SHARED_LINKER_FLAGS "${CMAKE_SHARED_LINKER_FLAGS} /NODEFAULTLIB:MSVCRT /NODEFAULTLIB:MSVCRTD")
> endif ()</span >
LIBCMT and LIBCMTD are ignored for WinCairo port.
But, they are the static CRT.
