You have been subscribed to a public bug:
Impossible to use DBI with DBD::mysql on Ubuntu 10.04.1 LTS.
I get Segmentation fault of Perl when exiting the script.
It seems that there is an internal destructor for DBD which is called on
script exit which produce this segfault error.
I can repeat the error at any time.
Here are the details:
