Message-ID: <15995.5739.187550.62688@cuddles.cambridge.redhat.com> (raw)
In-Reply-To: <15994.60290.676217.25116@cuddles.cambridge.redhat.com>
I've beeen playing with this in an attempt to find a workaround, and
it's such a mess that I don't think it's worth it.
Consider this:
---------------------------------------------------------------------
#include <stdio.h>
class Boof
{
int arse ()
{
return 25;
}
void *prickle;
};
class foo : Boof
{
public: long long i;
};
int main ()
{
foo f;
fprintf(stderr, "offset: %d\n", (char *)&f.i - (char *)&f);
fprintf(stderr, "alignof: %d\n", __alignof__(f.i ));
return 0;
}
---------------------------------------------------------------------
Run it on x86, and you get:
offset: 4
alignof: 8
We can't leave it like this.
Andrew.
