if kernel is built w/ gcc-3.4.4 and -Os (at least I had that for 2.4.x kernels) it "optimizes away" memcmp and the kernels have gotten a patch to overcome this, the same problem does not occur w/ gcc-3.3.x. > > So I think its a bug in gcc version 3.4.4 (Gentoo Hardened 3.4.4-r1, > > ssp-3.4.4-1.0, pie-8.7.8) > > > > Makes me nervous because I have built everything with -Os. I have built everything w/ -Os and do not have trouble w/ it Peter -- Peter S.
