I cloned from http://hg.nginx.org/nginx http://hg.nginx.org/nginx to try and reproduce with your configure arguments, but i actually error out elsewhere; src/http/ngx_http_request.c: In function ‘ngx_http_set_virtual_server’: src/http/ngx_http_request.c:1955:32: error: ‘cscf’ may be used uninitialized in this function [-Werror=maybe-uninitialized] cc1: all warnings being treated as errors which i'm not interested in following up. My `ngx_string.o` did build successfully though. Using gcc 4.7.2 on Debian 7 Are you using a new CPU with an old(er) gcc version? Try specifying -march explicitly instead of native.

  Doh. I recently moved this VM from a C2D to an i5 machine. And this is on Ubuntu 12.04 which is old enough not to know about this newer CPU. Still, it should not crap out like that...

    Just as a follow up, I tried this with no -march flag and it compiled just fine. This is with gcc 4.6.3.

  This error seems to be caused -Werror compiler flag.

I haven't had issues, but I'm only using -O2. I also have to do "-march=native -mno-avx -mno-aes" because I'm on a Xen instance that doesn't allow the avx/aes instructions.
