So it looks the same .I do not have one SkJumper_generated.o build by gcc to
compare it with .
Somebody have one ?

Title:
Firefox crashes at start on armv7L after 55.0.1 update
Status in Mozilla Firefox:
Expired
Status in firefox package in Ubuntu:
Confirmed
Bug description:
Firefox always crashes when launched after the 55.0.1 update on an
Orange Pi PC Plus (a single-board computer similar to a Raspberry Pi),
even in safe mode.
I did a fresh install of Armbian (a Ubuntu Xenial 16.04 re-spin for
ARM single-board computer) on a similar board (Orange Pi Plus 2e),
installed Firefox and experienced the same problem--it won't load
without crashing.
