https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=276170

--- Comment #12 from dmilith <dmilith@me.com> ---
Also, it's 100% reproducible. Even from the sh file:

#16:11:12 vks5-14-0 /tmp λ cp
/Software/Python312/.src_34340eab1ef9bee6/Python-3.12.1/code.profclangd ./
#16:11:37 vks5-14-0 /tmp λ sh ./pegen_errors-927930.sh
Expected<T> must be checked before access or destruction.
Expected<T> value was in success state. (Note: Expected<T> values in success
mode must still be checked prior to being destroyed).
PLEASE submit a bug report to https://bugs.freebsd.org/submit/ and include the
crash backtrace, preprocessed source, and associated run script.
