Can you isolate the individual source file from the build, triggering the issue? And can you reduce the included headers from there, to only including libc++ headers, triggering the issue?...

Ok, I've reproed that. But when I try the same, I'm also getting another error, which also is present when building with a release: ``` In file included from SSHSession.cc:35:...

I have heard similar reports before - it’s a false positive. If those who are affected wants to report it, to get rid of such false positives, that’d be appreciated!

I can reproduce this; it seems to only happen when using msvcrt, not ucrt. It happens when using `__USE_MINGW_ANSI_STDIO=1`, with msvcrt, when the calling object file is compiled as C++,...

FWIW, I posted patches to mingw-w64, that should avoid this issue now, at https://sourceforge.net/p/mingw-w64/mailman/message/58821747/.

This issue should now be fixed in the latest release that was made yesterday.
