I've got a CoreMIDI driver that had worked just fine in 10.2, but crashes
the CoreMIDI server in 10.3. In debugging the code, it appears that in
trying to launch our server application from our CoreMIDI driver (via Apple
event stuff, or GetCurrentProcess calls, or LaunchApplication), the Carbon
call to the OS never returns, and the CoreMIDI server crashes (there is no
crash log that I can find, though). If I use the launch services API such
as LSOpenFSRef to launch our application, the same thing happens. All I see
is "RegisterProcess failed error=-50" in the console output. If I comment
out all calls to launch our server, the driver loads and functions
correctly.
All of this worked fine in 10.2. I thought the drivers were loaded into the
CoreMIDI server application space, but I am not sure if they are loaded at
application level, or the kernal level. Are some APIs no longer available
for CoreMIDI drivers? What has changed with the CoreMIDI server from 10.2
to 10.3?
Thanks,
