Just hadn't gotten to that part yet, thanks for the reminder.  Fixed.

verified after syncing that my test case is now fixed.

(Would close, but not sure why Jason didn't close it... please close if there's
nothing else to do, Jason, or tell me to.)

Decided to try to verify again with current head of trunk compiler (since
several other bugs I reported have been fixed, and one was related to value
initialization).

gcc version 4.4.0 20081201 (experimental) (GCC) 

configured/built same way as before.

This error still occurs.  (FYI.)

The relevant change in DR 178 is

   To value-initialize an object of type T means:

  * if T is a class type (clause 9 [class]) with a user-declared
constructor (12.1 [class.ctor]), then the default constructor
for T is called (and the initialization is ill-formed if T
has no accessible default constructor);

The default constructor for derived should call the default
constructor for base.  The base constructor is defined in another
file, and so any incorrect code in the base constructor should be
flagged in another compilation.

DR 178 changed some of the behavior here and I think what GCC is doing is now
the correct behavior according to that Defect report.
