GNU/Linux
Architecture: i686

        
host: i686-pc-linux-gnu

Here is a source:

/* strcat.c */
char *strcat(char *d, const char *s)

    while (*d) d++;
    while ((*d = *s) != '\0') { d++; s++; }
    return p;
}
------- Additional Comments From namsh at kldp dot org  2004-03-12 01:56 -------
Fix:
        1.  Do not use '-fomit-frame-pointer'
        2.  Use '-O2' instead of '-O3'.
