Comment 3 for bug 192134

I would like to repost my previously deleted bug by (lazy IMHO)
<email address hidden>. The math sin function is at least 1000x slower on 64bit
distributions for special numbers (and carlos dosn't care about it).
I can't try it with CVS head, because I cannot connect to cvs through our firewall.
But even when I tried the latest snapshot, I couldn't build it (maybe another bug):

Please, anyone with 64bit distribution and glibc CVS head, could you try the
attached example and post the time results of it? (or help me to build the
snapshot...)
Thank you

====== Original bug report ======================================
The math sin(double) function is in 64bit distribution (Kubuntu 7.10 AMD64 and
Fedora - unknown version) unreasonable slow (~400 microseconds on Atlon64 X2
4800+!!!) for some special values. In 32bit distribution is everything fine.
I captured some of those values:

Example:
#include <math.h>
int main(int argc, char** argv) {
    volatile double value = 0.93340582292648832662962377071381;
    volatile double out;
    int i;
    for (i=0; i < 20000; i++)
        out = sin(value);
    return 0;
}
