Have you tried a recent gcc 4.7 build on slack to see
if there has been any change to the kwrite crash (bug 979) issue. Apparently,
there is 1 build on Fedora 17 that works, but all builds on gcc 4.7 on my end
have failed with the exact same reproducible bug. Isolating this is way beyond
what I can do from a debugging experience level.
I haven't tried building with 4.7 because Slackware Current still has 4.7.0. In other
words, nothing has changed.
I notice a 4.7.1 release is expected Real Soon Now. I hope Slackware updates respectively.
Let me know whether you see any announcements that 4.7.1 is released. I'll then ask
the Slackware maintainer to update although he might say no (many other packages have to
be rebuilt with a gcc change).
I don't know what magic Francois is using with Fedora 17.
Can you run the TWin4 game, nee KWin4?
