In addition, I get a segfault if I use a single-quoted string rather
than a double-quoted string. (My understanding is that single-quoted
strings are normally used to reference symbols, so this should be an
error but not a crash)
$ /usr/bin/gdb -batch -p $(pgrep -nx R) -ex "print (char*) getenv('oops')"
