Thank you __so much__ for digging through this!
R comes with three regexp engines (three, as the count goes: old pre-POSIX,
POSIX [ and both those from libc as I recall] plus pcre). Obviously the
default is broken and switching to pcre helps.
I am just a little worried that maybe we get a side effect on other
systems. Shall we maybe protect this by an architecture test? What does this
say on these arm* machines?
R> Sys.info()

"edd"

R> Sys.info()["machine"]
machine
"x86_64"
On the other hand, the use inside the install should be fine ...
