I was unable to reproduce this test locally with the case provided and the same ASAN_OPTIONS and cmdline args (albiet on linux).

+mmoroz@ -- this also looks like another instance of huge logs (26k+ lines) in the report.

WontFix due to no local repro.

Sounds good, thanks for the heads up! We'll fix the issue with long logs for non-reproducible crashes.
