| Subject: | Segmentation fault when fetchrow() is called too many times |
Hi,
DBD::SQLite2 crashes with a segmentation fault when fetchrow() is called
again after it has returned an empty list (ie. the query has completed).
Please consider the attached testcase. It crashes with 0.33 on both Perl 5.8.4 and 5.8.7 on Debian GNU/Linux 3.1 ("sarge") and unstable ("sid").
This bug report was originally filed as Debian bug #317453, http://bugs.debian.org/317453
Cheers,
