Yes, I will open a bug for this.

For the archives, The original error message from Perl Mapscript was:

*** 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):

and the problem ended up being that the symbol directory was missing and 
it was having heartburn trying to access png symbol

We diagnosed the problem by moving to shp2img which reported:

loadSymbol(): Unable to access file. Parsing error near 
(../markers/sm_square.png):(line 73) <br>

which lead me to check if the markers directory was loaded. It wasn't 
and loading that directory solved the problem.
