This used to work and I can't explain why it should be failing in this case. It is really pretty generic C code. The only purpose of this test is to assure that a structure is initialized properly. It does seem like a compiler issue. Could it believe that dummyfunc() is an ARM (vs Thumb2) function? Sorry. I'm no help on this one. -- This is an automated message from the Apache Git Service.
