[cfe-dev] Is this an over alignment bug for ARM?

I think that's valid. The "long long" member means that the entire
class must be 8-byte aligned (under AAPCS), in particular the this
pointer itself. And then there are 4 bytes of padding between mBaseLen
and mOffset to ensure mOffset actually is aligned.

Or am I misreading something?

Cheers.

Tim.
