Richard, so what exactly is not kosher?
We have:
# DEBUG D#7 => &s.c.D.2422
...
MEM[(struct J *)&s].D.2422._vptr.G = &MEM[(void *)&_ZTV1JI1BIwES0_IS1_E1AIS1_EE
+ 16B];
in the optimized dump, &s.c.D.2422 is ADDR_EXPR of COMPONENT_REF of MEM_REF,
the first operand in the real stmt is COMPONENT_REF of COMPONENT_REF of
MEM_REF.
