This is related to this bug fix:
CHANGES IN R 3.6.1 patched BUG FIXES
‘options(warn=1e11)’ is an error now, instead of later leading to C
stack overflow because of infinite recursion.
which occurred in rev 77226. It explicitly coerces the warn value to

It is changes in the dev and patched versions, and also your mistake:
your test shouldn't be so stringent. The docs don't say that the value
has to be a double; in fact, they suggest it should be a whole number
value (talking about 0, 1, "2 or more", not about what would happen with
options(warn = pi/2), for example.
In older versions, options(warn = pi/2) is treated the same as
options(warn = 1), and in the new version, it is displayed as 1 as well.
