Curiously, the much more straightforward


import mapnik

def mktrans(source, target):
    source = mapnik.Projection(source)
    target = mapnik.Projection(target)
    trans = mapnik.ProjTransform(source, target)
    return trans

box = mapnik.Box2d(-5, 55, 35, 67)

source = '+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs'
target = '+proj=merc +ellps=WGS84 +datum=WGS84 +no_defs'

trans = mktrans(source, target)

print trans.forward(box)

also crashes, but if I inline the mktrans function it does not crash.
