Memory leak when exporting in MP3 format
When repeatedly exporting an MP3s of several different MuseScore files. I noticed that the memory used by MuseScore increased with each export. The memory used increased while the export was active but failed to return to the previous value after each export.
This came to my attention when MuseScore crashed twice as I was performing the exports. There were several exports between crashes. The Windows Task Manager shows an increase of around 200,000 K after each export completes. The size of the MuseScore file didn't seem to have a significant effect on the amount of memory leaked. It was about the same for a large 90 kB MuseScore file with 205 measures in 6 staffs and with a small 26 kB MSCZ file with 4 staffs and 52 measures.
