 Oh, right. So, this crash is reproducible from the last upstream 52.8.0ESR
 commit:
 {{{
 commit 0ce659a05fd3fefeead88d4ef0b35ec497c07415
 Author: Lee Salzman <lsalzman at mozilla.com>
 Date:   Sun Apr 29 20:10:51 2018 -0400

     Bug 1454692 - Backport some upstream Skia fixes to ESR52. r=rhunt,
 a=abillings

     --HG--
     extra : histedit_source :

 }}}

 and that crash results in:
 {{{
 F/libc    ( 6367): Fatal signal 11 (SIGSEGV), code 1, fault addr
 0xfffffff0 in tid 6485 (JS Helper)
 }}}

 But I still have a corrupt stack.

 With mozconfig:
 {{{
 $ cat .mozconfig
 ac_add_options --enable-application=mobile/android
 ac_add_options --target=arm-linux-androideabi
 ac_add_options --with-android-ndk="$NDK_BASE" #Enter the android ndk
 location(ndk r10e)
 ac_add_options --with-android-sdk="$SDK_BASE" #Enter the android sdk
 location

 ac_add_options --disable-debug
 ac_add_options --disable-debug-symbols
 }}}
