Ive just stumbled on something weird with march=native: At some point I had march=prescott on a core2 E4600 running 32bit - worked well. Changed to march=native and did some upgrades with a few odd things like asterisk segfaulting in a glibc library afterwards, and some things not building. Then to add confusion, I changed to an pentium Duo E6600 (flies!) and added another stick of ram. More odd things happening such as reiserfs oopsing on shutdown. Last night the penny dropped and I looked the new processor up and changed to march=core2 and have mostly corrected (recompiled) the damage. So not sure about march=native now as it is only what was built with native thats been problematic. With 20-20 hindsight it was perhaps predictable ... BillK
