The culprit is the new zlib-1.2.5. This version requires newer libxml2-2.7.7, but this package hasn't arrived in -Current yet. Robby Workman posted a link in this thread and i found it working. After compiling libxml2-2.7.7 from source using Slackware's SlackBuild script, i don't get any segfaults anymore in VMWare.
So, for those who wanted to upgrade to -Current, you have two options:
- Upgrade libxml2 as well to libxml2-2.7.7 or
- Skip zlib-1.2.5 package for now and stick with 1.2.3
