BUG: /lib/lists.c.. Don`t use -O2 . Use -O1

[Lauro, John]

gcc 3.4.3?  

-O2 is generally pretty safe.  Your version of gcc sounds pretty old.  I assume this isn't an issue with newer versions of gcc?

I found that my trouble exists when compiling with -O2 option.
In that case inline functions rem_node and add_head will merged into
function (/nest/iface.c ifa_recalc_primary) and then will badly
optimized by compiler, because the implicit use of pointers to the same
data. If we call external function(like printf) between rem_node and
add_head trouble gone away in any case.

Now i use -O1. This works for 1.3.2 and 13.8.


My compiler is:
$ powerpc-nsg-linux-gcc -dumpversion
3.4.3
$ powerpc-nsg-linux-gcc -dumpmachine
powerpc-nsg-linux
