This looks as though it is related to the recent patch in
https://bugs.r-project.org/show_bug.cgi?id=18232
I think you should probably wait until that settles down before worrying
about it.

Dear R wizards,
I have recently been informed about some build errors of my package QCA,
which I was able to trace down to the base function substitute(), with the
following replication example:
foo <- function(x) return(substitute(x))
In the stable R version 4.0.5, I get the expected result:
foo(A + ~B + C~D)
A + ~B + C ~ D
A different result (the culprit for the build error) occurs under Fedora
with R devel:
foo(A + ~B + C~D)
A + (~B + C) ~ D
The Fedora machine is the rhub docker image from:
https://hub.docker.com/r/rhub/fedora-gcc-devel
probably very similar to the one signalling the CRAN build error:
https://cran.r-project.org/web/checks/check_results_QCA.html
The first (expected) command is from the stable R version installed on the
same Fedora machine, and I get an identical result on Windows and MacOS.
For some reason, substitute() gives a different result on Debian using gcc,
and on both Fedora systems. I would be grateful for any hint, I am not
entirely certain what I should do about this.
Thank you very much in advance,
Adrian
