HWAddressSanitizer CHECK failed: [...]/compiler-rt/lib/hwasan/hwasan_thread.cpp:117 "((random_buffer_)) != (0)" (0x0, 0x0) #1242
Description
I got the following report from HWASAN. The error "((random_buffer_)) != (0) looks like failed assertion inside hwasan, not anything to do with my code. In addition, there is nothing from my code in the stack trace.

This is deterministic, happens on every run. The option halt_on_error=false is not working, there is one more test that is not being executed.
When I run with HWASAN_OPTIONS="random_tags=false", I get a clean run of the tests until the end, without any errors.
I still haven't looked into producing the prepossessed reproducer sources. I'll update the ticket when I have that.
