Oct 1, 2025October 2025 (EVerest/everest-core) focused on stability improvements through a targeted bug fix: Musl-detection-based stack size auto-adjustment. The change automatically detects musl-based systems by inspecting ldd output and, when detected, increases the executable stack size to 8MiB by adjusting linker flags during build. Detection uses find_program to locate ldd and runs ldd on a test binary to determine the environment. This reduces stack-related crashes in low-default-stack environments (e.g., Alpine-like images) and eliminates manual runtime configuration. The work is committed under 6d1c9efd04b74dae3d2b1dfdace94dac2c20ac08 (Fix: detect musl-based systems and increase stack size), tied to issue #1422.
