[knro]

Please debug via Ekos Debugger and submit the crash backtrace.

[arakeis]

ok, will give it a try

[arakeis]

here are the two logs files from ekos debuger (indi tab)

app.indi.debug.log
indi.debug.log

on my side :
unpark mount
goto nearby ncp
sync -> crash

[knro]

2025-01-31T11:59:11: Driver indi_lx200_OnStep: *** stack smashing detected ***: terminated

So it crashes here but unfortunately, all I can tell is that it happens somewhere in ISNewNumber but nothing more specific. Can you recompile INDI from Github and test again?
