--- Comment #1 from William Cohen <wcohen at redhat dot com> ---
What specific compiler and openssl source were used to create the reproducer?

If tls_process_client_hello is really a partially inlined function, then it
should be skipped and the probe be place in the inlined piece of
tls_process_client_hello.  However, there doesn't seem to rest of the function
listed as a regular function (DW_TAG_subprogram) or inlined
(DW_TAG_inlined_subroutine) in the debuginfo,but there is a
DW_TAG_GNU_call_site:
