SubjectSIGBUS while compiling

ugluk:~/linux# make zImage
make[2]: Entering directory `/root/linux/kernel'
gcc -D__KERNEL__ -I/root/linux/include -Wall -Wstrict-prototypes -O2
-fomit-frame-pointer -fno-strength-reduce -pipe -m486 -malign-loops=2
-malign-jumps=2 -malign-functions=2 -DCPU=586 -c -o dma.o dma.c
gcc: Internal compiler error: program cc1 got fatal signal 7

ugluk:~/linux# gcc -v
Reading specs from /usr/lib/gcc-lib/i486-linux/2.7.0/specs
gcc version 2.7.0

note that signal 7 != signal 11 (sigsegv). signal 7 = sigbus.
this makes me think that the compiler is addressing longwords on
non-dword boundaries. does linux make use of the AC processor bit
at all ?
