Trying to add a bassoon and a French horn

No problem adding a Bassoon, or any Horn (there is none by the name of French Horn though)
MuseScore 3.4.2, Windows 7
Edit: darn, adding a Horn in F and I get a crash
Edit 2: and now with Bassoon too, strange
Firering up a debug build now...

Inititial observation, loading that score into a debug build I get the following message many times:
Warning: reorderMidiMapping: no part in master score is linked (...\libmscore\midimapping.cpp:146, void Ms::MasterScore::rebuildExcerptsMidiMapping())
Looks suspicious somehow, and related to the score/part relationship
Adding Bassone on hitting OK I get this stack trace:

Code at stack level 3 is that inner for loop:
With
sllbeing0, so a null pointer gets dereferenced -> kaboom!So indeed related to links between score and parts.

band aid for that crash is to check for nullptr before using it:

Also crashes MuseScore 3.3.4
(I haven't upgraded yet.)
Deleting all the parts allows adding instruments without the crash.

Indeed, see below
Crashes in latest master too

I can add instruments if first removing all parts.
A first possible workaround...

Score with recreated parts
In reply to Trying to add a bassoon and… by williamsilk1
How did you create that score? Almost all date in File > Score Properties is empty, including Platform and Creation date, which are automatically filled on score creation

So this brings us back to this question
Looking deeper into that score seems to show that it had been imported from an earlier version of MuseScore, I guess MuseScore 1.x (which didn't have linked parts)
Is that the case? Do you still have the score before importing it into 3.x?
In reply to So this brings is back to… by Jojo-Schmitz
yes it was created ages ago with early musescore. my orchestra is growing and wanted to resurrect this piece.
ok thank you will redo each part.
thank you

Can you share the old version? Needed to make sure we can fix that crash the right way.
Also please tell us what you did to is after the import, as detailed as possible
In reply to Trying to add a bassoon and… by williamsilk1
Culprit seems to be the 2nd Dwarsfluit part (why 2 of them?), so removing just that prevents/avoids the crash already.

There is 3.4.2 available meanwhile, but I don't see it to fix an issue that looks like your's, see https://musescore.org/en/handbook/developers-handbook/release-notes/rel…
Crash fixed in the latest development build and as such in next release
