Package: libmad0 Version: 0.15.1b-11+b1 Architecture: armhf Description: On Raspberry Pi 2 running Debian Trixie (armhf), libmad.so.0 requests an executable stack (GNU_STACK RWE). This causes alsaplayer, when trying to load the library, to fail with: libmad.so.0: cannot enable executable stack as shared object requires: Invalid argument
Workaround: Rebuilding libmad0 with '-z noexecstack' clears the GNU_STACK executable flag and fixes the issue. Suggested fix: Consider patching the ARM build to not require an executable stack. $ uname -a Linux rednode 6.12.47+rpt-rpi-v7 #1 SMP Raspbian 1:6.12.47-1+rpt1 (2025-09-16) armv7l GNU/Linux $ lsb_release -a No LSB modules are available.
