--- Comment #2 from Elliot Saba <staticfloat@???> ---
It does not appear to be inlined. Running the segfaulting case in `lldb`
yields:
```
$ lldb -- ./.libs/pcre2test -q -S 16 -8 ./testdata/te
stinput2 testtry
(lldb) target create "./.libs/pcre2test"
Current executable set to './.libs/pcre2test' (x86_64).
(lldb) settings set -- target.run-args "-q" "-S" "16" "-8"
"./testdata/testinput2" "testt
ry"
(lldb) r
