If you are using the AUBase C++ classes to build your AudioUnits, you will find the DISABLE_DENORMALS & RESTORE_DENORMALS macros in the code.
The HAL does not disable denormals, so it is only by luck if you are getting this mode in a HAL ioProc.

by luck? what kind of luck would accidentally reset the processor to do this (or not) ? this should be process/task local, no? do you have in mind some other software component that might set them (or might not)?
