crash in Curl_getaddrinfo_ex using libcurl 8.11.1

Hi,
A program that has been happily using libcurl for years
started crashing when we upgraded libcurl from 8.10.1 to 8.11.1.

I was hoping the good folks here might be able
to point me in the right direction; the crash is within a libcurl 
getaddrinfo call.
A sample gdb stack trace is at the end of the email.

- the OS is Ubuntu 22.04.5 LTS.
- there were no code changes in the program, just dependency updates
- the program is multi-threaded

Based on the fact that 'getaddrinfo' is mentioned in the stack trace, I 
wonder if this is somehow related
to a PR that was merged into 8.11.0: https://github.com/curl/curl/pull/15475

Thanks for any help! And let me know if any other information would be 
useful.
