Sending the crash through asan_symbolize.py gives: Executing /home/gk/asan/mozilla-esr24/obj-x86_64-unknown-linux-gnu/dist/bin/xpcshell -g /home/gk/asan/mozilla-esr24/obj-x86_64-unknown-linux-gnu/dist/bin/ -a /home/gk/asan/mozilla-esr24/obj-x86_64-unknown-linux-gnu/dist/bin/ -f /home/gk/asan/mozilla-esr24/toolkit/mozapps/installer/precompile_cache.js -e precompile_startupcache("resource://gre/"); ASAN:SIGSEGV ================================================================= ==4017==ERROR: AddressSanitizer: SEGV on unknown address 0x000000000000 (pc 0x000000000000 sp 0x2b9955a94738 bp 0x2b9955a947f0 T2) AddressSanitizer can not provide additional info.
