    * Any ideas how upgrading the X server now calls into openssl?
       I've bisected this error down to the change in the X server
       recipe to v1.19 from v1.18.4


$ grep ssl *
xserver-xorg.inc:XORG_CRYPTO ??= "openssl"
xserver-xorg.inc:PACKAGECONFIG[openssl] = "--with-sha1=libcrypto,,openssl"

The X server took the reasonable approach of refusing to reimplement 
cryptographic functions and instead relies on an
external library, of which openssl (well, libcrypto, part of openssl) is one 
option.

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.
