Bug ID: 120282
Summary: -Warray-bounds triggered incorrectly
Product: gcc
Version: 14.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: dominick.allen1989 at gmail dot com
Target Milestone: ---

preprocessed file after cvise reduction and gcc info
I could not make a minimal replication of this without putting my original code
through cvise. I find the cvise output hard to understand, so I am not sure how
valuable it is.
The bug is triggered with `-std=c++20 -O3 -pthread -Werror=array-bounds`, but
adding `--coverage -fsanitize=address,undefined` makes it go away. In the
original code.
I can provide additional context if desired, but it is not a minimal case.
