After Bug 11998, fastmmap caching system implementation in Koha::Cache ceased
to work properly. If fastmmap is enabled (= environment variable CACHING_SYSTEM
is set to 'fastmmap'), any CGI script call causes the following error:

Use of uninitialized value $db_name in concatenation (.) or string at
/home/koha/devkohaclone/Koha/Database.pm line 73.
Use of uninitialized value $db_host in concatenation (.) or string at
/home/koha/devkohaclone/Koha/Database.pm line 73.
DBI connect('database=;host=;port=','',...) failed: Access denied for user
'koha'@'localhost' (using password: NO) at
/usr/share/perl5/DBIx/Class/Storage/DBI.pm line 1249
DBIx::Class::Storage::DBI::dbh(): DBI Connection failed: Access denied for user

/usr/share/perl5/DBIx/Class/Storage/DBI.pm line 1253. at
/home/koha/devkohaclone/Koha/Database.pm line 90

To reproduce on command line:

0) ensure that you have fastmmap perl module installed (libcache-fastmmap-perl
in debian)
1) export CACHING_SYSTEM=fastmmap
2) export GATEWAY_INTERFACE=1
3) try to run this simple script:

#!/usr/bin/perl

use Modern::Perl;
use C4::Biblio;
GetMarcStructure();
