This happens when the ABI is (was) imprecise. Earlier versions did not special
case long double complex, but the current version does. Hence I have a patch
ready that partly reverses the original change (actually, implements the
original behavior for this type in a form slightly closer matching the ABI
definition); expecting to submit this later today or tomorrow (currently
building/testing).
As to the same(?) problem observed with float complex: I doubt the mentioned
patch causes this, since behavior for that type wasn't modified by it.
