Apache 2.4.57 will probably be put into vote this weekend. It will fix a crash in mod_http2 with mod_fcgid, which is present in 2.4.55 and 2.4.56.

For those of you that run into this: apply https://github.com/apache/httpd/commit/d6a9e4 or (in patch form) https://github.com/apache/httpd/commit/d6a9e4.patch and recompile Apache.

Thx @Jan-E!
I was digging around mod_fcgid crash since few days and was not aware of the fix...
I've applied it, fresh compile and will check if all sounds good now with php 8.2.4 as fcgid on httpd 2.4.56, mod_h2 2.0.13, mod_fcgid 2.3.10 with some fix
