On Mon, Oct 30, 2006 at 01:32:18PM -0800, Paul Johnson wrote: See attached output. Thanks, that's helpful. There seems to be something going wrong outside fetchnews but there does look to be a problem in fetchnews itself. Could you please generate a valgrind trace against a fetchnews binary with debug symbols? You can do this by rebuilding the source package and then running valgrind against the fetchnews binary in the source tree. To get the packages needed to do the build install things needed to do the build: apt-get build-dep leafnode apt-get install leafnode then get the source package and compile it: apt-get source leafnode cd leafnode-2.0.0.alpha20061010a dpkg-buildpackage -rfakeroot -us -uc -B and finally run valgrind on the resulting fetchnews binary: valgrind -v ./fetchnews If you're not comfortable with doing this please say and I'll upload something for you to try somewhere when I'm on the correct machine. -- You grabbed my hand and we fell into it, like a daydream - or a fever. signature.asc Description: Digital signature

Sorry, I should also have asked: could you please try running fetchnews with verbosity turned up: fetchnews -vvv (it's probably as well to do this outside of valgrind; if you don't feel comfortable with the debug symbols stuff this should be at least as useful). -- You grabbed my hand and we fell into it, like a daydream - or a fever. signature.asc Description: Digital signature

Is there any noob docs for this? I'm not a developer; valgrind isn't something I know. I was able to test these packages succesfully so it appears that there is something different about your systems which is triggering the problem. Given that it looks like memory corruption hopefully valgrind will be able to identify it. If it helps, running fetchnews/leafnode with env MALLOC_CHECK_=0 fetchnews (or leafnode) seems to work perfectly. -- Paul Johnson Email and IM (XMPP Google Talk): [EMAIL PROTECTED] pgpwKiKbQO1Nf.pgp Description: PGP signature
