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?
