--- Comment #2 from Manuel López-Ibáñez <manu at gcc dot gnu.org> ---
With such a large testcase, it is difficult to say. GCC seems to think that the
use is unguarded:
[WORKLIST]: add to initial list: extra_332 = PHI <extra_734(D)(228),
extra_235(15)>
[CHECK]: examining phi: extra_332 = PHI <extra_734(D)(228), extra_235(15)>
[CHECK]: Found unguarded use: _600 = extra_332 + _599;
Perhaps we are hitting some limit, perhaps it is a bug. Perhaps both. Hard to
tell.
In any case, there are so many known Wuninitialized bugs and no one to fix them
that it is probably something known. I really would not bother about reporting
more Wuninitialized bugs unless you can show it is a regression. It is simply
not worth your time. Better put together all those minutes that you would spent
reporting them and fix a known one or convince someone to fix it ;-)
