CI: disable -O2 for Coverity after v9.1.0429 Commit: https://github.com/vim/vim/commit/95ff39f8e3d5e16d4ef55f47d8f50da29df05f9e Author: Christian Brabandt <cb@256bit.org> Date: Wed May 22 07:53:23 2024 +0200 CI: disable -O2 for Coverity after v9.1.0429 gcc -O2 outputs this warning and turns it into an error when running Coverity action: ``` eval.c: In function ?echo_string_core?: cc1: warning: function may return address of local variable [-Wreturn-local-addr] eval.c:6495:12: note: declared here 6495 | char_u buf[MAX_FUNC_NAME_LEN]; | ^~~ ``` This seems to be a false positive, so disable -O2 for Coverity specifically.
