A crash at startup is mostly because of stale objects files hanging
around. I think you should do a "make clean" in src/FDM/JSBSim and
remove src/FDM/JSBSim.o and try again.

This gets fixed by this patch:

Ths problem is that GearPos is decreased to it lowest maximum value
somewhere in the retraction code.
I suspect there is a check for == 0 where < 0.01 would be more apropriate.
