Ticket details:
If I download the installer from SourceForge (https://sourceforge.net/projects/
mingw/files/Installer/mingw-get-setup.exe/download ), run it, and when I get to
the MinGW Installation Manager GUI I choose to install msys-dos2unix, version
7.4.0 gets installed
If I download the installer from OSDN (https://osdn.net/projects/mingw/
downloads/68260/mingw-get-setup.exe/ ), run it, and when I get to the MinGW
Installation Manager GUI I choose to install msys-dos2unix, version 7.3.2 gets
installed.
Running mingw-get update, then migw-get upgrade, doesn't seem to affect the
version installed.
Curiously, looking at my local copy of msys-dos2unix.xml (C:\MinGW\var\lib\
mingw-get\data\msys-dos2unix.xml), I see dos2unix-7.3.2-1 as the most recent
version, whereas in the source code online (https://osdn.net/projects/mingw/scm
/git/mingw-dist/blobs/5a8b6b0ff835e46186af512c4adbc0cbd96662ba/msys/
msys-dos2unix.xml ), dos2unix-7.4.0-1 is the most recent version.

Comment:
Due to my misinterpretation of Microsoft's documentation, the mingwrt-5.3
implementation of btowc() may incorrectly return 0xFFFD, when it should return
WEOF, if the byte to be converted is not valid as a single byte character in
the active codeset. This is corrected, in the repository, for whenever
mingwrt-5.3.1 is published.

Ticket details:
I'm using MinGW-gcc-6.3.0. The wcsrtombs() function as mentioned in the docs on
cppreference 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
Currently working around by passing INT_MAX as the length parameter, so it
finishes within the limit and returns the size.
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 :)

Comment:
I've identified a further issue, this time with the mingwrt-5.3 implementation
of mbsrtowcs(); if the cumulative count of wide characters stored reaches
exactly one less than the nominated buffer length, and conversion of the next
multibyte character results in a surrogate pair, this is stored anyway, causing
a buffer overrun by one wide character. This too, is now corrected in the
repository, for inclusion in mingwrt-5.3.1.
