// ================================ Requirements ===============================
// This function is required to be either implemented by the supporting
// allocator, or one of the two provided implementations may be used
// (RTGwpAsanBacktraceLibc or RTGwpAsanBacktraceSanitizerCommon).
// ================================ Description ================================
// This function shall collect the backtrace for the calling thread and place
// the result in `TraceBuffer`. This function should elide itself and all frames
// below itself from `TraceBuffer`, i.e. the caller's frame should be in
// TraceBuffer[0], and subsequent frames 1..n into TraceBuffer[1..n], where a
// maximum of `Size` frames are stored. Returns the number of frames stored into
// `TraceBuffer`, and zero on failure. If the return value of this function is
// equal to `Size`, it may indicate that the backtrace is truncated.
// =================================== Notes ===================================
// This function may directly or indirectly call malloc(), as the
// GuardedPoolAllocator contains a reentrancy barrier to prevent infinite
// recursion. Any allocation made inside this function will be served by the
// supporting allocator, and will not have GWP-ASan protections.
