Thanks, I missed that.

That said, this wasn't really related to the problem anyway.
libcrypt causes that illegal instruction - on purpose - to
check for certain hardware capabilities and handles it.  Just
running 'continue' in GDB lets the X server get a lot further.

I was able to isolate the problem down to a data structure being
trashed.  I'm not sure yet how/why, but I think there may have
been some important changes that the i.MX6 Vivante hardware
driver isn't currently up to speed on.  Still investigating.
