Description Martin von Gagern 2010-05-16 17:52:19 UTC

Executing attached script will cause perl to panic, i.e. print a message and abort execution:

panic: sv_len_utf8 cache 3 real 11 for bаr and bāz at <FILENAME> line 33.

The script will require the following setup:
* dev-perl/DBD-mysql installed
* some mysql server up and running, might be remote
* a database "test" on that server, which I guess many default setups have
* credentials for accessing that server saved in your ~/.my.cnf

So far I've failed to reproduce this without DBI, or with different database backend drivers like dev-perl/DBD-SQLite-1.29-r2. Might well be specific to the mysql perl driver implementation.

As the subject might get adjusted in the long run, here is my config:
* dev-lang/perl-5.10.1
* dev-perl/DBI-1.611
* dev-perl/DBD-mysql-4.01.4

Demo script

This script should demonstrate the issue. Let me know if it doesn't for you.

Perhaps https://rt.cpan.org/Public/Bug/Display.html?id=53130 is related to this here. Unfortunately no fix available there yet.
