MapServer 4.6.0-beta2 64bit Perl/Mapscipt Problem

[Stephen Woodbridge]

Hi all,

I have a user that has installed MapServer 4.6.0-beta2 ( we are also 
trying with beta3 ) and built Perl Mapscript, But it is dying with:

*** glibc detected *** double free or corruption: 0x00000000012817c0 ***
 
mapscript::mapObj::new(/usr/lib/perl5/site_perl/5.8.5/x86_64-linux-thread-multi/mapscript.pm:1408):

The code works fine on another system with a 32bit CPU, but this box has 
  a 64bit AMD chip in it and is running suse 9.2 - standard install.

Is this a known problem? is there a work-a-round?
