Bug ID: 275014
Summary: audio/linux-c7-alsa-plugins-oss: fails to build with
-enable-trivial-auto-var-init-zero-knowing-it-will-be-
removed-from-clang
Product: Ports & Packages
Version: Latest
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: Individual Port(s)
Assignee: emulat...@freebsd.org
Reporter: s...@rogue-research.com

Flags: maintainer-feedback?(emulat...@freebsd.org)
I build my own packages with poudriere.
I recently globally added the clang
`-enable-trivial-auto-var-init-zero-knowing-it-will-be-removed-from-clang` flag
and that broke `audio/linux-c7-alsa-plugins-oss` from building. The other 419
packages I build had no problem.
The error is:
```
checking for gcc... gcc
checking whether the C compiler works... yes
checking for C compiler default output file name... a.out
checking for suffix of executables...
checking whether we are cross compiling... Segmentation fault (core dumped)
configure: error: in
`/wrkdirs/usr/ports/audio/linux-c7-alsa-plugins-oss/work/32/alsa-plugins-1.1.6':
configure: error: cannot run C compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details
*** Error code 77
Stop.
make: stopped in /usr/ports/audio/linux-c7-alsa-plugins-oss
```
The `-enable-trivial-auto-var-init-zero-knowing-it-will-be-removed-from-clang`
flag has a dubious name I agree, but that's only because FreeBSD 13.2's clang
14 is rather old. In newer clang the flag was promoted from experimental to
fully legit and is now named `-ftrivial-auto-var-init=zero`. See
https://discourse.llvm.org/t/making-ftrivial-auto-var-init-zero-a-first-class-option/55143
My reason for using the flag is the same as others: security. Android, Chrome
OS, Windows, Apple, and others use this in production builds too.
>From the error output, I would guess that something is building and running a C
program to test something, and that program is crashing.
