what are the next few libc calls after those strlen() calls ? any hint what might go wrong in my case ?

Even the currently developed openSUSE version is going to be shipped with a lot of issues, since we're busy with SLES/SLED. What is more frustrating for a bug reporter? Never get any response - or - a least a status update (+ a plan how to address that issue for the next openSUSE release)? Harald, luckily every openSUSE user is now part of the openSUSE community and therefore is able to branch a package, apply the patch, submitrequest it, i.e. trigger an update to fix the issue. In case you're interested in doing this, please let me know, so we can reopen the bug, reassign it to you and ask the maintenance team for an update.

https://bugzilla.novell.com/show_bug.cgi?id=631994 https://bugzilla.novell.com/show_bug.cgi?id=631994#c16 --- Comment #16 from Ulf Lange <mopp@gmx.net> 2013-09-16 17:26:56 UTC --- After reading my post twice I found the solution. The problem is the client compression which used the zlib. I used UltraVNC with auto detection for format and encoding. These encodings will crash Xvnc: ZRLE, Zlib, ZlibHex, Ultra, CoRRE, ZYWRLE and u2. They are all based on Zlib. An workaround is to use a different encoding, e. g. hextile works fine. Does somebody have an idea how to fix it? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
