Thanks for finding this! http://distrib-coffee.ipsl.jussieu.fr/pub/linux/Mageia/distrib/4/SRPMS/core/release/memtest86+-5.01-5.mga4.src.rpm also have other interesting fixes, BTW. However I have issues with the patch: -O0 disables quite a lot of optimisations, and we surely don't want to disable all those that are not buggy. I haven't looked in depth, but the additional required changes are probably a consequence of this. Additionally, we don't even know what the gcc problem is, ir even if it has been reported to the gcc team. Having more detailed information would allow to link to 2 problems. If nobody has the detailed info, I'll try to find the time this week to identify the faulty flag. Best regards, -- Yann -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
