[Bug c++/38297] O2 causes invalid code

[pinskia at gcc dot gnu dot org]

------- Comment #4 from pinskia at gcc dot gnu dot org  2008-11-28 02:20 -------
Yep you are violating C++ aliasing rules as you are accessing a char * as an
unsigned char*.  It would be ok if you accessed a char as an unsigned char but
you are accessing the pointers instead.

It is not the size which matters but rather the types which are being accessed
here.
