#1602 Bus error on starting rosegarden

[Dikus]

I compiled last code:

Rosegarden version: 21.12 ("Cloud Nine")
Build key: df5432c9b8 (21.06-21-gd2ff1d4c9)
Built against Qt version: 5.11.3

in a raspberry pi 4 and when I start rosegarden I have:

...
[main] Creating RosegardenMainWindow instance...
[Composition] getTrackById( 0 ): WARNING: Track ID not found.
[Composition]   Available track ids are:
qt.qpa.xcb: QXcbConnection: XCB error: 147 (Unknown), sequence: 175, resource id: 0, major code: 140 (Unknown), minor code: 20
Bus error (core dumped)

Debugging it seems that this assignement fails:

Thread 1 "rosegarden" received signal SIGBUS, Bus error.
0xf776b2ce in Rosegarden::MappedEvent::operator= (this=0x7ce5d1, mE=...) at /rosegarden/src/sound/MappedEvent.cpp:165
165         m_eventTime = mE.getEventTime();

Sorry but I'm not a programmer and I don't know if it is meaningful.

Bus errors could be caused by a number of things:

1. Bad SD card.
2. Running out of physical memory.
3. Running out of virtual memory.
4. Running out of SD card space.
5. Bad power supply.

Use the "top" command to monitor physical and virtual memory usage. "df -h" will give you an idea how much free SD card you have. If memory or SD card seem low, try another bigger SD card. That might clear this up.
