I have exactly the same problem hacking squid code under 4.0-CURRENT
and 5.0-CURRENT. Basically, inside the dns routines a variable
would be corrupted between a couple of non-relevant lines, and cause
squid to segfault after trying to resolve

That -O is safe seems to be a persistent myth. GCC also produces
broken code for -O and no optimization in some cases, sometimes while

A very quick example of why big -O3 gcc optimizations are a bad thing?
my /etc/make.conf has
USA_RESIDENT=NO
CFLAGS=-O3 -pipe -mcpu=pentiumpro -march=pentiumpro -fomit-frame-pointer
NOPROFILE=true
(NOPROFILE=true because profiled libraries fail to build with no frame pointer)
now, cd

FWIW, I understand that they carry pgcc (http://www.goof.com) which may
be very risky under Linux. Linus doesn't even recommend the latest gcc
because he likes to keep his kernel dependent on the old (non-standard)
features.
Look in the archives, I recall someone benchmarked the new gcc on this

Why exactly whould you not touch the -march options? I have had no
problems using them, and my system (5.0-CURRENT) seems a little faster
with -march=i686. I could be wrong though as I havn't done any exact
tests... it just seems a bit more responsive..
