ELF init_priority only orders constructors within a single module. All of a shared object's initializers run before any of the executable's, so an instrumented dependency .so emitting a zone from its static initializer creates the main thread producer token against the zero-initialized s_queue. The queue constructor then resets the producer list, orphaning that producer: every zone emitted on the main thread from that point on is enqueued into blocks no consumer ever iterates and silently lost, while sampling (worker thread producer) keeps working. Re-link such a producer right after the queue is constructed. In the common case, where nothing was emitted during shared object init, this merely constructs the main thread token eagerly.
Tracy Profiler
A real time, nanosecond resolution, remote telemetry, hybrid frame and sampling profiler for games and other applications.
Tracy supports profiling CPU (Direct support is provided for C, C++, Lua, Python and Fortran integration. At the same time, third-party bindings to many other languages exist on the internet, such as Rust, Zig, C#, OCaml, Odin, etc.), GPU (All major graphic APIs: OpenGL, Vulkan, Direct3D 11/12, Metal, OpenCL, CUDA.), memory allocations, locks, context switches, automatically attribute screenshots to captured frames, and much more.
