Hi, sorry, but I had no luck with 0.49, there were some stack overflow and off-by-one bugs sleeping since longer time, but now rising up during compiling with some protection options. Many credits to Radek Vokál for finding bugs and pointing out the snprintf size problems. Therefore I released now version 0.50: Available at: <ftp://ftp.bieringer.de/pub/linux/IPv6/ipv6calc/> (and via CVS - note that DS6 currently contain only older versions). Not-minor changes: 20050915/PB various c files - fix snprintf size parameter (credits to Radek Vokál for pointing this out) lib/libipv6addr.c#ipv6addr_copy - fix bug which causes stack overflow (credits to Radek Vokál for finding the bug) several Makefiles - add compiler switch -O2, reason for segfault was found - remove also static on clean ipv6logconv: - add support for unique local unicast update databases Happier using now...
