(In reply to comment #2)
There are going to be other holes in structs in general due to
alignment
requirements and I don't think the compiler or libstdc++ should
change to this
because it will slow down the generated code and not really makes a
difference
in the outcome of the code.
Purify already handles pad bytes added for alignment correctly.
This is a very
specific case, where the pad byte is added to prevent the struct
from having
size zero, not for alignment. The added code to clear 1 byte, at
object
constuction time, would not make any significant performance
difference.
But it can cause code bloat which can cause performance issues because
of icache sizes and such.
