just compiled the current trunk version, to test guitar tablature.
When I try to create a score with a guitar staff + a guitar tablature staff (via the File->New menu), a crash occurs.
Here is the gdb log:

Title [Trunk] Musecore hangs while creating a guitar tablature ⇒ [Trunk] Creating a guitar tablature causes crash

I can't reproduce - must have since been fixed, perhaps.

Please re-open if you still have problems.

Using MuseScore 2.0 Nightly Build (5497) - Mac 10.7.3.

chen --

what did you do to try to reproduce? looking at the original bug report here, the submitter of this bug is (or was, at the time) operating a 64-bit linux build. did you test it on a 64-bit linux build of trunk? i ask because this sounds (and looks) very similar to the problem I've reported, and he's running on the same type of system I am.

as an aside, I don't think it's very accurate to flag a bug as "fixed", simply because you didn't reproduce the error. "closed" I could believe (if not agree with), but certainly not 'fixed", as no patch was submitted specifically against this bug report.

no, that's not the crash i'm referring to. I'm referring to the other (also previously closed) ticket that describes, essentially, exactly what happens in the description for this (also closed) bug.

if you don't plan on fixing it, don't care, or whatever -- that's fine. just mark it as "won't fix", and I'll be out of your hair.
