I may have found the issue:
When I spin an AIR application from WebHelp output and
preview the AIR application, or
when I Preview an application from the AIR Packager Generate
dialog,
if I Cancel the dialog before I close the AIR application,
the OS will BSoD every time;
if I Cancel the Generate dialog without first closing the AIR
application, the AIR Packager exits and returns control to me
without error, every time.
This sounds like a memory management bug of a garbage
collection bug.
When I close the fresh AIR application before I exit the AIR
Packager, apparently the AIR Packager attempts to clear memory,
finds that <some address> is already clear, and barfs with
"PAGE_FAULT_IN_NONPAGED_AREA" every time.
