Since egcs-1.0.2 appears to be the default Linux compiler, at least
if one looks at,
it may be better to find such wrong code generation problems.
I have produced a combined source/disassembler of the file
linux/net/ipv4/tcp_ipv4.c and placed it at

I could recompile the kernel with another compiler, but since I have
no way to reproduce the bug this could only be useful if I happen
to see the bug again in a kernel compiled with another compiler. In
that case we would know that the bug is not compiler-related.
