Details

The current recommended mozconfig for address sanitized builds recommends that --disable-elf-hack is enabled. has_elfhack is false on anything but Linux and as a result --disable-elf-hack is not an option and an exception will be hit on configure.

The severity field is not set for this bug.
:Sylvestre, could you have a look please?

Did the build succeed without the --disable-elf-hack option?

Flags: needinfo?(choller) → needinfo?(drobertson)

Yeah, the build succeeds without the --disable-elf-hack option, so a simple note in the docs like the following could work:

# ASan specific options on Linux
ac_add_options --disable-elf-hack
