[Flightgear-devel] route manager crash

[Tobias D. <tda...@gm...>]

Hi,

I noticed that the route manager causes a crash when trying to append
waypoints to a route that ends in a holding position.

Now, holding positions cannot currently be defined in the UI, but I'm
using XML definitions from
https://github.com/fgx/fgx-airports/tree/gh-pages/LDS767_AIO_Individual_XML_Airports

Many of these have missed-approach procedures and/or STARs that end in a
holding position (which is nice - then you can actually fly them under
ATC, and if you fail to get clearance to proceed, the aircraft will just
stay in the hold until you click "next waypoint", and when you execute a
missed approach procedure, you'll automatically end up in the hold, and
then ATC can vector you back onto an approach).

However, selecting a STAR that ends in a hold (e.g. VEVAR6R for LFMN),
and then selecting an approach, or vv., leads to the following error
message and crash:

fgfs: /home/tobias/src/flightgear/src/Navaids/routePath.cxx:649: void
RoutePath::RoutePathPrivate::computeDynamicPosition(int): Assertion
`previous->posValid' failed.

FGFS version is 2018.3, compiled from source on amd64 Debian 9; I was
flying the CRJ1000ER when it happened, but I would expect other planes
to crash as well. Haven't tried though.
