Log Message:
Make a gcc 4.8 warning non-fatal (couldn't find a way to avoid it, the
data is initialized via memcpy to a void pointer, so the may be
uninitialized
warning is not true)
If the problem actually caused by gcc failing to pair all the conditionals?
Compiling with 'clazz' a compile-time constant might show things.
Or, if memcpy() is defined in a header file and uses casts to optimise
inlined copies of fixed sizes it might be that the pointer-aliasing
rules mean that the actual structure might not have been written.
A possible solution to that is an asm statement with a memory
constraint for the buffer areas either side of the actual copy.
