Does compiling with -O2 -fno-strict-aliasing fix the issue.  I thought I saw
some aliasing violations in the source dealing with accessing a "char *" as a
"Log_event::Byte*" (aka "unsigned char *").  Now what is only defined is the
accessing anything by a char/unsigned char/signed char, accessing pointers via
a different type is undefined.  The function which I saw the issue is in
copy_str_and_move where there are going to be accesses in those two types.
