So is this the ASAN version of bug 904227 (which hasn't gone anywhere)?

There is one case where ASan failures are usually not s-s, and that is if it's a regular SIGSEGV (indicated by the "SEGV on unknown address") at or near NULL. That's the equivalent to a regular null-deref crash. ASan just catches regular SIGSEGVs for convenience reasons, but usually this means that a normal build would also crash. If that's not the case, then it's usually due to memory layout differences etc. In all other cases (use-after-free, buffer-overflow, SEGV on weird addresses, etc.) these bugs are usually s-s. Based on the trace above I assume this is not s-s, thanks though for checking with us! :)

I think we should dupe this against 904227. I'll take a look at 904227 next week.
