Revdep issue with vctrs about winch HOT 6 CLOSED

It's fixed in the devel version, for a CRAN release I'll need to get rid of the warning at https://cran.r-project.org/web/checks/check_results_winch.html. Does that ring a bell?

FWIW, I worked around in b450b7e. This issue is a real mess.

Fixed on CRAN now.

This looks like the issue of Microsoft's clib not conforming to the C standard. The mingw toolchain reproduces the Microsoft behaviour. You can set a variable to use the gcc version instead. But even then you might still get false positive warnings about it in some cases.
