--- Comment #3 from Giuseppe D'Angelo <dangelog at gmail dot com> ---
Hello,

I'm actually not sure; running gdb on the binary and stepping through
instructions leads me to __sin_fma:

(gdb)  bt
#0  __sin_fma (x=3D5.1836278784231586) at ../sysdeps/ieee754/dbl-64/s_sin.c=
:202
#1  0x00005555555550d9 in main () at test.c:30

This is on Ubuntu 20.04 on a Broadwell CPU.
