A caught signal (the handlers are inherited by the child) delivered between PTRACE_TRACEME and exec first produces a signal-delivery stop; without handling it, the setup would run on the still pre-exec child and capture the monitor's own image as the target's. Re-inject the caught signal and wait again until the exec stop is reached. Job-control stops are the exception - re-injecting SIGSTOP/SIGTSTP re-stops the child, and PTRACE_CONT rejects a stop carrying the 0x80 job-control bit - so resume those without a signal instead.
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 graphics/compute APIs: OpenGL, Vulkan, Direct3D 11/12, Metal, OpenCL, CUDA, WebGPU.), memory allocations, locks, context switches, automatically attribute screenshots to captured frames, and much more.
