Hi. HEAD code looks broken; if I go back about 40 hours it works correctly. There's some dangling reference (fails unpredictably on malloc/free). I'm trying to trace the problem; Kurt's reworking of the DN stuff should be OK, while I'm a bit worried about the DN ber scanning as 'o' instead of 'a' (and I'm not sure I know what I'm talking about ;-). I'll try to apply all the changes step by step. Ando.
