1579290 - ASAN builds should disable LSAN while building

Status: RESOLVED FIXED

(NSS :: Build, defect, P1)

Description

[Martin Thomson [:mt:]]

We've had a couple of LSAN failures recently in CI that report something like:

==60+==HINT: LeakSanitizer does not work under ptrace (strace, gdb, etc)

It appears that the root cause of this is that the binaries were built with LSAN enabled. The resulting binaries then trigger some syscall that the updated CI environment blocks.

I don't really understand how this would happen, but https://hg.mozilla.org/integration/autoland/rev/471550ac81dccd22b7d7e12c2978187b67198e32 shows that disabling LSAN during the build seems to work for gecko builds. We can use the same fix.
