Description Martin Jambor 2024-07-26 15:14:20 UTC 
GCC 14 newly by default treats as errors a number of situations which
before were only warnings.  For more information see
https://gcc.gnu.org/gcc-14/porting_to.html and meta bug #1220571.

Because of this, package clang-extract fails to compile.  This can be
seen online at:
https://build.opensuse.org/package/live_build_log/home:rguenther:plgrnd/clang-extract/openSUSE_Factory/x86_64

It can be reproduced locally with command: osc build --clean
--alternative-project home:rguenther:nextgcc

The (first) error that stops the build is:

Comment 1 Giuliano Belinassi 2024-07-26 15:22:28 UTC 
This issue is found in the testsuite and the test is intended to handle implicit types, hence such errors shall be silenced rather than changing clang-extract testcase.

An issue for this was open in clang-extract: https://github.com/SUSE/clang-extract/issues/96
