This appears to be failing within setenv() which (as far as I can tell) is being passed a perfectly valid string. setenv() is supposed to fail gracefully and set errno to ENOMEM if it doesn't fit in the environment but apparently isn't. I believe the environment size is limited by ARG_MAX on POSIX-like systems, but it's not usually tested by the caller (which doesn't know how much space is left). -- Peter Stephenson <p.w.stephen...@ntlworld.com> Web page now at http://homepage.ntlworld.com/p.w.stephenson/ -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
