This is a fragment from the Squid configure file (from the original
2.4-STABLE1 distribution):
# Remove optimization for GCC 2.95.[12]
# gcc -O[2] on *BSD and Linux (x86) causes pointers to magically
become NULL
if test "$GCC" = "yes"; then
GCCVER=`$CC -v 2>&1 | awk '$2 == "version" {print $3}'`
case "$GCCVER" in
2.95.[12])
echo "Removing -O for gcc on $host with GCC $GCCVER"
CFLAGS="`echo $CFLAGS | sed -e 's/-O[0-9]*//'`"
;;
esac
fi
This was probably written before gcc 2.95.3 got out, but I'm not sure
if that version fixed the problem. I have foolishly tried to compile
Squid with gcc 2.95.2 and optimization (both -O, -O2 and -O666), and
I can assure you it bombed out with inexplicable null pointer
accesses. Yet when you compile with -O0, no such thing happens...
Maybe it's best to ask the Squid maintainer(s) if gcc 2.95.3 is
supported with optimization.
