Bug ID: 104084
Summary: [12 regression] Internal compiler error: tree check:
expected target_expr, have compound_expr in
build_new_1
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: linux at carewolf dot com
Target Milestone: ---
Another error encounted while compiling Qt with gcc 12. This time in libgav1
(used by Chromium).

Disabling optimizations or using different C++ standards, or fuzzing other
compiler flags didn't seem to help.
Let me know if you need the intermediate code.
