I've attached a revised summary of the critical bugs open against 4.0. The good news is that there are fewer than last week.
Earlier today, Andrew Haley posted a small C++ snippet showing an ABI change
affecting gcj on PPC32:

I hope he'll open a PR soon, but you probably want to consider this for 4.0.
Note it also effects all targets too by shown by my testcase. Also I think it was caused by: 2004-06-21 Mark Mitchell <[EMAIL PROTECTED]>
* cp-tree.def (NEW_EXPR): Add a fourth slot.
* cp-tree.h (PARMLIST_ELLIPSIS_P): Remove.
(TREE_PARMLIST): Likewise.
....It also shows that the C and C++ ABIs for the struct I had in the testcase
no longer matches so it is even worse than just gcj.
Testcase:
#include <stdio.h>
typedef struct Parent
{
long long m;
int *scratch;
void * __attribute__((aligned(8))) this$0;
}Parent;
int main (int argc, char **argv)
{
printf ("%d\n", sizeof(Parent));
return 0;
}Thanks, Andrew Pinski
