…pen-telemetry#36252) The root of the crash reported in open-telemetry#36179 was the fact that the `Buffer` struct being passed by value in recursive calls made it allocate the needed amount, but, after the return of the recursive call it attempted to read a buffer that was larger than the allocated buffer on the recursive call. The crash was going to be hit whenever an XML was larger than the default size of the buffer (16KiB). The code is a bit hard to test because its fully usage actually happens on the receiver where the buffer and its components are not visible. I'll look to add a test in a follow-up. cc @djaglowski Skipping changelog since open-telemetry#36179 covers it. --------- Co-authored-by: Daniel Jaglowski <[email protected]>
