This test just checks for the stdout/stderr of clang, but it incidentally tries to write to `a.out` in the current directory, which may be write protected. Typically one would write `clang -o %t.o` for a writeable dir, but since we only care about stdout/stderr, throw away the object file and just write to /dev/null instead. >From b23bfe788d2fba00f8303c54e53507a8fd0bc53b Mon Sep 17 00:00:00 2001 From: Jordan Rupprecht <ruppre...@google.com> Date: Wed, 10 Apr 2024 11:50:04 +0000 Subject: [PATCH] [clang][test] Avoid writing to a potentially write-protected dir This test just checks for the stdout/stderr of clang, but it incidentally tries to write to `a.out` in the current directory, which may be write protected.
