segmentation fault on shutdown with dbd

["ernst schoen-rene" <ernstsr@xxxxxxxxx>]

When I shut down apache via apachectl top, it gives me this error

/usr/local/apache2/bin/apachectl: line 77:  5034 Segmentation fault      $HTTPD -k $ARGV

the log reports

[Fri Jan 02 10:28:51 2009] [notice] seg fault or similar nasty error detected in the parent process

If I take mod_dbd and mod_authn_dbd out of the compile, there is no problem.  

This is apache 2.11 on fedora 64.

Anyone else experience this?
