Crash on MacOS With Enttec DMX USB Pro

[jeffc3nc]

Hi,

I've been creating a light system with QLC+ for an event I'm doing in January.

Have a late 2014 Mac mini with Monterey installed and an Enttec DMX USB Pro interface. QLC is the most recent Mac release.

QLC is fabulous. I quickly learned how to define and control my lights. But I'm getting a sporadic crash. It will happen with nothing pressed in the window. Message is:

022-12-04 02:33:59.140125-0500 qlcplus[39097:1010536] It's not legal to call -layoutSubtreeIfNeeded on a view which is already being laid out. If you are implementing the view's -layout method, you can call -[super layout] instead. Break on void _NSDetectedLayoutRecursion(void) to debug. This will be logged only once. This may break in the future.
qlcplus(39097,0x1000a0600) malloc: Heap corruption detected, free list is damaged at 0x6000018b8b00
*** Incorrect guard value: 34359738373
qlcplus(39097,0x1000a0600) malloc: *** set a breakpoint in malloc_error_break to debug
(lldb)

In several cases I got this traceback in the error dump:

I thought I might be a build/libs issue, so I got the source from Git and installed the prerequisites and built (Version 4.12.7 GIT). But I still get the crash.

Any ideas?

Have been running using Xcode memory error detection tools, but haven't found anything.


Thanks,
Jeff
