Yes, I have the same problem. You can avoid this by deleteting "-pipe" in
This cause segfault:
gcc -S -D__KERNEL__ -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer \
-fno-strength-reduce -m486 -malign-loops=2 -malign-jumps=2 \
-malign-functions=2 -pipe -c m.c
m.c can be "void f() { }" or something else.
At this time, I don't know what is bad, but you can:
1. Use kernel compiled for 386
2. Comment that "-pipe"
3. Get another gcc, not from RH 4.1 but 4.0 (I'm not sure about this, but
I also have no problems before installing 4.1)
