Description
For example, psbasemap is trapped forever in the loop (GMT_eckert4):
do {
sincos (phi, &s, &c);
delta = -(phi + s * c + 2.0 * s - (2.0 + M_PI_2) * s_lat) / (2.0 * c * (1.0 + c));
phi += delta;
}
while (fabs(delta) > GMT_PROJ_CONV_LIMIT && n_iter < GMT_PROJ_MAX_ITERATIONS);
Perphaps because GMT_PROJ_CONV_LIMIT is small for 32 bits or because n_iter never gets incremented.

Yes, it works for me, and I get the same map in 32 and 64 bits. Thanks!
