Dear Ladies and Gentlemen, It appears that doing something more obvious with STDERR (such as re-opening it in a BEGIN sub) gets rid of the SEGV.
I am not sure why I used a tied filehandle for handling STDERR (apart from solidarity with STDOUT, which does need the tie because the required processing is completely different from a normal filehandle). Sorry for the noise. Yours sincerely. -- Stanley Hopcroft IP Australia Ph: (02) 6283 3189 Fax: (02) 6281 1353 PO Box 200 Woden ACT 2606 http://www.ipaustralia.gov.au
