All,
I am pleased to announce that DBD::SQLite (Self Contained RDBMS in a Perl DBI
Driver) version 1.26_05 has been released on CPAN (by Adam Kennedy).
..
P.S. DBD::SQLite has at least 1 known bug, also in version 1.25, with regard to
full-text search (FTS3); there is an included new failing test, which currently
is set to skip so the CPAN testers don't issue fails,
I tried to create a db with FTS3 and got the following
perl(12546) malloc: *** error for object 0x1eb160: Non-aligned pointer
being freed (2)
*** set a breakpoint in malloc_error_break to debug
perl(12546) malloc: *** error for object 0x870200: double free
*** set a breakpoint in malloc_error_break to debug
perl(12546) malloc: *** error for object 0x1ea668: Non-aligned pointer
being freed
*** set a breakpoint in malloc_error_break to debug
Segmentation fault
Is the above the FTS3 related error?
Looks similar. This is the official bug report that we already have, which was
reported on Oct 14, and on which the failing/skipping test is based:
http://rt.cpan.org/Public/Bug/Display.html?id=50503
Subject: Segfault with fts3
A copy of the ticket text is displayed below the dashed line in this email also.
The bug report was against DBD::SQLite versions that bundled SQLite 3.6.13 and
3.6.18 respectively, for both of which the bug manifests.
As of yet the bug is unfixed.
If you have any new information, it would be useful for you to add it to the
above RT ticket.

The attached script fails on 1.25 and 1.26_04. It does one of three things:
- segfaults
- gives a double free error
- hangs without any cpu activity
Which of the above three it does depends on the exact script (adding or
removing a print line can change its behavior), but it always fails.
Here are a couple sample error messages:
*** glibc detected *** double free or corruption (!prev):
0x000000000083c480 ***
Abort (core dumped)
Segmentation fault (core dumped)
The database doesn't appear to be corrupted after the failure -- running
an integrity check with the sqlite3 command line binary says the db is okay.
The equivalent code without the fts3 module works fine.
I did a quick test with the DBD::SQLite packaged with the latest Ubuntu
(1.14), and that version seems to work.
