 Hello once again...

 Attached is a program to compute the convex hull of a multipoint geometry.
 Compilation fails (msvc).

 Compilation works if either a polygon is used instead of a multipoint, or
 the convex_hull function is not called.

 Compiler output pasted below.

 Many thanks for developing this useful library, I hope this is me failing
 to use it correctly rather than problems your end!
