1/* Linker version script for libwebrtc.so (Linux only).
 2 *
 3 * When libwebrtc.so is built with rtc_use_pipewire=true and
 4 * -fvisibility=default, PipeWire lazy-load trampoline stubs (pw_*, spa_*)
 5 * are exported as weak symbols. If the PipeWire ALSA plugin
 6 * (libasound_module_pcm_pipewire.so) is later dlopen'd by libasound,
 7 * the dynamic linker may resolve the plugin's pw_* references through
 8 * libwebrtc.so's broken trampolines instead of the real libpipewire.so,
 9 * causing a SIGSEGV (NULL function pointer dereference).
10 *
11 * This script hides only those third-party symbol namespaces while
12 * keeping every WebRTC / BoringSSL / internal symbol exported (which
13 * the Rust webrtc-sys bindings require).
