hybrid try/catch/leave crashing on hardware

Compile and run the attached test app on hardware. It will crash.
Investigation shows that in tst_test::test(), every line containing a TRAP(err, QT_TRYCATCH_LEAVING(.....)); causes problems. That is, hybrid traps are not working.
The code is valid and should not crash.
Compiled with ARMCC 2.2 686.
Tested on N78.

Using TRAP(err, ......); by itself does not crash in this code, but is not a general solution as a standard exception would crash it.
