It seems to be a glibc bug.  According to:

    https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=160759

the bug was already fixed by 2005-07-10.  Indeed, the libc/ChangeLog at:

    http://sources.redhat.com/cgi-bin/cvsweb.cgi/libc/ChangeLog?rev=1.9521&content-type=text/x-cvsweb-markup&cvsroot=glibc

has the following entry:

2005-07-07  Ulrich Drepper  <drepper at redhat.com>

        * sysdeps/generic/s_ctanh.c (__ctanh): Handle case of zero den better.
	* sysdeps/generic/s_ctanhf.c (__ctanhf): Likewise.
	* sysdeps/generic/s_ctanhl.c (__ctanhl): Likewise.
	* sysdeps/generic/s_ctan.c (__ctan): Likewise.
	* sysdeps/generic/s_ctanf.c (__ctanf): Likewise.
        * sysdeps/generic/s_ctanl.c (__ctanl): Likewise.

Looking at the diff in the sources we see that there is a better treatment
of the case where the denominator is equal to 0.0:

http://sources.redhat.com/cgi-bin/cvsweb.cgi/libc/sysdeps/generic/s_ctanh.c.diff?r1=1.2&r2=1.3&cvsroot=glibc&f=h
	
John, could you please confirm that this would fix the bug?
