Hello,
R 4.1.1 on Ubuntu 20.04.
I can reproduce this error but not ~90% of the time, only the 1st time I
run the script.
If I run other (terminal) commands before rerunning the R script it
sometimes segfaults again but once again very far from 90% of the time.

Hope this helps,

Here's a brief example:
# A bunch of words in UTF8; replace *'s
words <- readLines("h****://pastebin.c**/raw/MFCQfhpY", encoding = "UTF-8")
words2 <- iconv(words, "utf-8", "latin1")
gctorture(TRUE)
y <- match(words2, words2)
<The program crashes / segfaults ~90% of the time>
I searched bugzilla but didn't see anything. Apologies if this is already
reported.
The bug appears in both R-devel and the release, but doesn't seem to affect
R 4.0.5.
