I am attaching a more readable test case that takes the number of params as an argument. The issue seems to start at 2046 params for me, which is obviously near 2^11. With some values, I get segmentation faults rather than the error I included in my first message.
I am using Perl 5.16.3, and I tested it on multiple machines with both the MySQL and Pg drivers. Please let me know if you need any other information.
Here is the output of 'perl -V' on my home box:
