Greetings,
I am trying to validate an AU plug-in but auval is crashing
upon validation. The logs indicate a very suspicious behavior
on auval's part and I wonder if someone here has any experience?
Apparently auval is creating 2 instances for a validation. My log
files
are very detailed. I can destinguish between the instances by the
'this'
pointer.
No problems there.
Yes - this is correct, but only one instance is actually kept open
and validated. The reason we open the second is that we've seen some
problems with AUs that presumed their would only be one of them open
The problem is that auval is deleting one of the instances in the
middle
of testing it, and thus continue to test that instance after the ctor
has been called. How in the world can that be? Surely it is not a part
of the test? The result is obviously a segmentation fault.
No - we are only testing on the AU we've kept open. Perhaps you have
some shared state that are disposing in the destructor when the
second unit is closed (early on)?
If you go into the sample effect project (/Developer/Examples/
CoreAudio) and enable the DebugDispatcher, you can trace the various
calls it makes on which instances.

Thank you in advance. I appreciate any input :-)
PS: Intel 10.4.8, auval 1.1.2c11
