Pull request overview
Adds a targeted warning when a stripped libc is loaded without embedded DWARF and no separate debug file can be located, guiding users to install distro debuginfo packages so libc frames don’t show up as unknown symbols.
Changes:
- Emit a warning before failing when no DWARF and no separate debug file is found.
- Add libc-specific detection to suggest installing
libc6-dbg/glibc-debuginfo.
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.

When a stripped libc is loaded without a matching debug file (no .debug_info section and no match via build-id or .gnu_debuglink), emit a warning pointing users at libc6-dbg / glibc-debuginfo so they know why libc frames show as unknown symbols. Refs COD-2536
