Thanks, fixed in R-devel and R-patched.
The problem was only in unserializing of raw vectors serialized in
ASCII, the format is not affected. Old serialized ASCII files created by
R 3.5 or earlier can be read in R-patched and re-saved in binary format,
which can in turn be read in R 3.5 and
I see this on MacOS as well, so likely not platform dependent.
A little more diddling to try to narrow it down:
> unserialize(serialize(as.raw(1), NULL, version=2, ascii=TRUE))
[1] 30
> unserialize(serialize(list(as.raw(1)), NULL, version=2, ascii=TRUE))
[[1]]
[1] 30

I ran into an interesting error unserializing a file created with
ascii=TRUE:
R 3.5.1 (Windows or Linux):
> unserialize(serialize(list(raw=as.raw(c(39,41))), NULL, version=2,
ascii=TRUE))
Error in unserialize(serialize(list(raw = as.raw(c(39, 41))), NULL,
version = 2, :
