This warning will go away if you change your --fg-root to
--fg-root=/usr/local/share/FlightGear/data

Yes, CVS.  Data must match the binary, as sometimes there are changes to
the xml or nasal  syntax.

The warning message is new.  The fgfs binary automatically changes
FGROOT to $FGROOT/data if it doesn't find the data folder in $FGROOT
where it belongs.  However many tools break on $FGROOT/data so now the
fgfs binary issues a warning about a non-compliant $FGROOT.

This is not the source of your segfault.
