Ticket details:
I'm using MinGW-gcc-6.3.0. The wcsrtombs() function as mentioned in the docs on
cppreference (https://en.cppreference.com/w/cpp/string/multibyte/wcsrtombs)
should return the number of bytes that would have been written to src. However
it doesn't do so on my end. It seems the implementation doesn't ignore the
length parameter when dest is passed as NULL? A similar issue was reported and
presumably fixed for the Mingw-w64 on the sourceforge site (https://
sourceforge.net/p/mingw-w64/mailman/message/34751152/)
I apologize in advance if this is just an issue from my end or if any other
info is missing. First time submitting a ticket :)
