oh, this is a weird problem. Can you reproduce it? If so, could you
create a stack backtrace or a core-file for us? For that, you need to
compile with
  ./configure CFLAGS="-O0 -g"
and then tell the system to write a core-file if the daemon crashes:
  ulimit -c unlimited

The core-file will be in the `BaseDir' after the daemon crashed -
`collectd -h' will tell you the default value for `BaseDir'.

You can then create a stack backtrace using the GNU debugger, gdb:
  gdb /path/to/collectd /path/to/core

Unfortunately, straces are not a lot of help when hunting down a
segmentation fault :(
