Gizmo crashing X-Plane with illegal instruction error

[dpny]

Running Gizmo 10.3.8 on a G5, with X-Plane 9.45 and OX 10.5.8.

I tried Gizmo with the new P180 Avanti Alterna, which I think is the first plane I've used which uses GIzmo. The result was X-Plane quitting with an illegal instruction error. However, every time I launched X-Plane after it quit, it would quit within a minute of launching with the same error, no matter which plane I was attempting to open. The only way to stop this was to remove Gizmo from my plugins folder, at which time X-Plane returned to normal.

At first I thought it was the new Saitek control plugin, but removing that didn't solve the problem.

The very last crash was me attempting to open the P180 without Gizmo installed.

Hi,

Gizmo is not used for any aircraft with the exception of the Falco and the Cessna Corvalis.

Can you re-install Gizmo and post a log.txt from your X-Plane directory?

[Ben Russell]

...yeah, ok, I can see the error..

That avanti package is using a plugin called XAP. Probably part of that SASL plugin.

When the avanti loads its attempting to load XAP.

XAP contains Lua.

Gizmo also contains Lua but it's already loaded because Gizmo is installed at the system level.

When both items load into ram we ended up with two Lua engines inside X-Plane with the result being a core dump.

This is non trivial to fix and will probably affect all aircraft that are using the XAP/SASL system.

-sigh-

Re-installing Gizmo will do nothing to resolve this.

If you want to fly your Avanti the temporary solution is to disable Gizmo before you launch the sim that it it isn't loaded as a plugin.

Disabling Gizmo "in sim" "after loading" won't work.

Thanks for the bug report.... :/

[dpny]

At the moment the problem is solved, but not really: the developer of the Avanti told me that the XAP plugin he's using currently doesn't support PPC Macs, which I have, so I removed the XAP plugin from the Avanti folder. The plane is 95% flyable, with some odd error messages, and Gizmo is happy again.

One of these days, if the economy improves, I may join the rest of you in Intel land.
