Bug 122955: please open again
I had the same problem today, while recompiling a already running linux
kernel 2.4.16 setup. The only thing i changed was the processor
selection from 386 to Pentium-Classic (see configs below) and
Pentium-MMX in a second try. Both had the same error. With 386 settings
(-march=i386) and k6 (-march=k6) gcc is compiling without this problem.
I am using debian/woody with up to date packages from debian.org:
binutils 2.11.92.0.12.3
cpp-3.0 3.0.2-4
g++-3.0 3.0.2-4
gcc-3.0 3.0.2-4
gcc-3.0-base 3.0.2-4
gcc-3.0-doc 3.0.2-4
libc6 2.2.4-7
modutils 2.4.11-1
I can reproduce the bug and send further files/outputs. Please request
from rainer.ellinger@web.de
