Bug ID: 1727
Summary: arparse LTO warnings
Product: DPDK
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: other
Assignee: dev@dpdk.org
Reporter: stephen@networkplumber.org
Target Milestone: ---
Enabling LTO detects more warnings in argparse test.
Looks like argparse is referencing invalid arguments before checking.
