Environment

• OS: CachyOS (Arch-based)
• GCC version: 15.2.1
• Feather version: 2.8.1 (via AUR feather-wallet)

Description

Building feather-wallet from source via the AUR fails with GCC 15.
The error occurs in src/device_trezor/trezor/protocol.cpp at sort_ki().

Error

bits/stl_vector.h:112:35: warning: '_M_finish' may be used uninitialized [-Wmaybe-uninitialized]

hw::trezor::protocol::tx::Signer::sort_ki()
protocol.cpp:618

make: *** [Makefile:136: all] Error 2

Notes

• The official AppImage (2.8.1) works fine
• This is a GCC 15 compatibility issue, likely in the Boost/Monero submodule code
• The featherwallet-appimage AUR package is also broken, stuck on 2.7.0 with a dead download URL

Workaround

Using the AppImage directly from GitHub releases.
