Problem compiling kernel 2.6.6

[Chiheb Djabri]

Hi 

I tried to compile kernel 2.6.6 for the 4th time but it failed:

include/asm/io.h: In function `isa_check_signature':
include/asm/io.h:237: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://bugzilla.redhat.com/bugzilla> for instructions.
The bug is not reproducible, so it is likely a hardware or OS problem.
make[3]: *** [drivers/video/aty/radeon_accel.o] Error 1
make[2]: *** [drivers/video/aty] Error 2
make[1]: *** [drivers/video] Error 2
make: *** [drivers] Error 2

How can I solve this???
