I have been implementing some Altivec routines in a KEXT and have been suffering some stack corruption panics (in stack_detach), despite scouring the code for bugs. So I then went back to the plain scalar sources which has already been thoroughly tested and performs fine. Yet, I still had the same panic problems. It turns out that I left the -faltivec compiler flag on. Removing the flag and rebuilding the scalar version ceased the panics. I tried this with other KEXTs I had; adding the -faltivec flag even though the KEXT had no Altivec code. They then began panicing as well. It this a known bug? Anyone else seen this? _______________________________________________ darwin-kernel mailing list | darwin-kernel@lists.apple.com Help/Unsubscribe/Archives: http://www.lists.apple.com/mailman/listinfo/darwin-kernel Do not post admin requests to the list.
