Re: zend_hash_add_or_update flaw

Good to know. I already see you adjusted your patch accordingly. Thanks, Andi At 10:17 PM 12/6/00 +0100, Sascha Schumann wrote:

The second we put nDataSize as the third parameter we can say bye bye to any compiler optimization. This is of course, if we actually know (and I don't) if some compilers would optimize this.

    Apparently, GCC does that:

    $ gcc -O -c y.c z.c
    $ nm y.o
    00000000 t gcc2_compiled.
    00000000 T main
    $ nm z.o
    00000000 t gcc2_compiled.
    00000000 T main
             U memcpy

    y.c uses a constant, z.c a variable as third parameter to
    memcpy.
