Seems i can only reproduce it with the live package provided by Gentoo , even
though it does not apply any patches. If I configure and compile the current
GCC trunk by hand and with the same options the crash does not appear. I'm not
sure where the difference comes from but it seems to have been a false alarm.
Sorry for the waste of time. 

LC_ALL="C" gcc -v -s ppl.ii -O2 -flto -g
