Repro steps:
1) Launch debug build of Chromium with --enable-heap-profiling=native on macOS.
2) Add the extension TraceOnTap
https://cs.chromium.org/chromium/src/third_party/catapult/experimental/trace_on_tap/README.md?q=TraceOnTap&dr=C&l=1
3) Hit the trace button. 
4) Is (3) succeeds, repeat (3). Try giving Chrome an unclean shutdown and then running (3) again.
