Confirmed. The problem appears with gcc-3.4.4-r1 (stable branch) and both, vanilla-sources 2.4.30 (stable) and 2.4.32 (testing). I compiled everything with gcc-2.96 on a

Problem: I think the problem is the way in which gcc-3.4.4 manage recursive inlining. sg_fill is an inline function which call itself and 3.4.4 doesn't like that. Status: We have our gcc ninjas working on it, hope to have it fixed soon. Workaround: I think is only problem of gcc-3.4.4. I can compile it with gcc-3.3.2 just fine. Since gcc is installed slotted, probably everyone who updated the gcc compiler can change it using gcc-config and compile the kernel with an old gcc (if needed).
