Hi Mark:

These failures appeared on Darwin with the new parser:

native g++.sum g++.abi/vtable3a.C
native g++.sum g++.abi/vtable3b.C
native g++.sum g++.abi/vtable3c.C
native g++.sum g++.abi/vtable3d.C
native g++.sum g++.abi/vtable3e.C
native g++.sum g++.abi/vtable3f.C
native g++.sum g++.abi/vtable3g.C
native g++.sum g++.abi/vtable3h.C
native g++.sum g++.abi/vtable3i.C
native g++.sum g++.abi/vtable3j.C
native g++.sum g++.jason/template26.C

The symptom is a bus error in each case.  For template26.C, the
failure happens at:

and 'type' is:

I can send you preprocessed source if you wish.  I bet the problem is
with this line from stdio.h:

extern FILE __sF[];
