MuseScore github-musescore-musescore-a78eec8 crash

• Jan 24, 2015 - 10:31

When I try to delete the 6th voice in the score ("Tenor -- to be deleted") MuseScore crashes.
I'm running the latest Mac OS (Yosemite 10.10.1) on an iMac.

in the forum bugs may be discussed, determined whether it is a bug is a user problem, or an feature request etc. Or even a bug that had been reported already, and maybe even fixed in a later release.
And indeed sometimes bugs are picked from the forum directly and get fixed, but the formal way would be to submit an issue, (once it has been determined that indeed it is a bug and a new one)

quick check, here's the stack trace:

Reported now in #45266: crash on removing an instrument from a score

removes those last lyrics syllables in the last couple measures first (where you have lyrics in stanza 4 only), and it won't crash on deleting the score.
Not meant to be a fix, but a workaround and part of analyzing the bug ;-)
