SubjectSegfaults using xawtv
Hi...

I _hate_ to do this, but I couldn't find (except for a reference to
"others who have segfaults using glibc") no reference to this problem.
Insmod of i2c, videodev and bttv succeed without problems or any message
in /var/log/debug, messages or syslog.

Also, though I'm surely no expert, I tested a bit with gdb & such, and
suspect there may be a problem that's not directly xawtv/bttv related.

Any suggestions?

John
