I filed PR 22207 with the testcase.

Oddly, the gcc-3.4 in Debian unstable does not emit the warnings:

$ g++-3.4 spurious_uninitialized_testcase.ii -Wall -Werror -O2 -c

$ g++-3.4 -v

gcc version 3.4.5 20050613 (prerelease) (Debian 3.4.4-1)

...which implies one of the following:

- it's been fixed already on the 3.4.x tree
- one of Debian's patches addresses it
- it's cygwin/windows specific (though I can't see how that would be)
