I think this can be closed?
(I opened a missed-optimization PR instead - PR28643)

oops - I didn't notice it was open against 4.1.
So hopefully porting Victor's patch to 4.1 would fix it.

this bug looks very similar to PR28839 which already have a fix in
patch http://gcc.gnu.org/ml/gcc-patches/2006-08/msg01171.html

We need to check if above patch fixes PR26969 as well.
