Hi, Gentoo has recently switched no using position independent code generation and in addition to that maybe other updates as well like new version of gcc etc. Whatever has changed both 21.4 and 21.5 ebuilds now fail due to different reasons but both fail in the dump step ether by core dumping or by hanging for ever. I have create the following two tickets in the gentoo bug tracker where you will find some more info (but I can of course create more info if needed.) https://bugs.gentoo.org/639214 https://bugs.gentoo.org/639642 I have tried to compile with using the -fno-pie flag in order to go back to position dependent code but that did not do the trick. I need some suggestions on how to debug this and even better some ideas what can cause this and how to fix this. This is a show stopper for XEmacs on Gentoo since moving to the new Gentoo profile requires rebuild of all packages. Yours -- %% Mats
