Frames whose symbol data is shipped inline with the callstack payload
(sel=1, e.g. Lua-side stack entries) were being passed to
GetCanonicalPointer() in the AddCallstackAllocPayload() query loop,
tripping its sel==0 assertion. They have no native pointer to query
and were already registered in callstackFrameMap earlier in the same
function, so just skip them.
Regression from c704f909, which hoisted the per-call-site dedup into
QueryCallstackFrame(). Three of the four updated call sites were
equivalent before and after, because the old guard and the new one
keyed on the same value. The fourth, this one, was not: the old guard
tested the frame as-is and matched the entry inserted a few lines above,
short-circuiting before GetCanonicalPointer() ran. The new guard keys on
PackPointer(addr), so GetCanonicalPointer() must run first to compute
addr, and the assert fires.
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.
