Crash on r1636


Comments

Somehow i miss something as i cannot reproduce the problem and never saw it. In step #3 i understand you open the xml file. What does step #4 paste? Step #5 results in an empty canvas on my system. I tested only kubuntu and the windows version under wine.

CTRL-O opens the file browser in musescore, CTRL-V paste the http url into the file field and press Enter. I will load in the xml file over the net into musescore. After that CTRL-W which crashes MuseScore.

In Windows you can paste a URL of a file into the file browser and it automagically downloads it, saves it as a temporary file, and opens it. However this is unrelated to the crash.

When I open and close any file on the local file system MuseScore crashes.

In rev. 1642 i fixed a memory corruption which happens on deleting a score. This may fix the crash on removing a score with ctrl+w. I still cannot reproduce it even on windows. Sometimes this kind of bug depends on the exact memory layout of the binary to get visible.

I can reproduce with r1642. I just open Adeste and close the tab, Ctrl+W or mouse in the top right corner.
How can I investigate further?

Status (old) active fixed

The memory consumption fix in r1644 seems to fix this bug. I'm uploading a windows prerelease.

just tested on XP and it looks ok. r1645 fixes another bug related to this + undo/redo. Reloading a file confused the undo stack.
