Indeed, however the new patch does not prevent the ICEs.

AFAICT the basic problem is not with p->sym->declared_at.lb, but with
p->sym->name. I have tried to check for p->sym->name==0 which happen sometime,
but not always in a seemingly random way.

When p->sym->name!=0 and an ICE, p->sym->name seems malformed. So I suspect a
bug upstream where the pointer p->sym->name is not reset to NULL.

BTW your patches do not follow the gnu coding style.
