How does that belongs in our mantis? It's a bug in LTO and all documents say that LTO is experimental, so no one is to blame yet. |

afaik LTO is seen as stable seens gcc 4.6. have you any reference about that? I found only "Combining -flto with -g is currently experimental" in the docs. as many other projects seems to compile well... i see this bug report as not fixable + recheck later if it works |

Gentoo install still warns you when you enable the USE flag. Also 4.6 is the first version where LTO has a _chance_ to build (before it failed in >>50% of the cases). |
