Comment:
This was caused by the problem reported at #10064. The `arctan2()`
automatic evaluation function checks if the second argument is positive,
line 1062 of `inifcns_trans.cpp` in pynac:
{{{
// atan2(0, x), x real and positive -> 0
if (x.info(info_flags::positive))
return _ex0;
}}}
attachment:trac_10062-doctest.patch adds a doctest to check this.
