bug in defined type default initialization

Tobias and Aleksander,

The only relevant patch that I can see is on April 19th - my fix for
PR35959.  This was applied to 4.3 as well.  It also falls out of the
revision range that you mention.

Indeed it is a nasty bug.  Strangely my trunk and 4.3 both give the
same, correct result.

gcc version 4.3.1 20080428 (prerelease) (GCC)

and

gcc version 4.4.0 20080502 (experimental) (GCC)

Both on Cygwin/i686

Puzzled
