The test case duplicates part of what is going on in my program.
The problem is when the program exits, you get the following error. On OS X, you get a different, but similar error. Both errors complain about double free memory or deallocating memory inside a block.

You need two files (attached) to run the test case. Just drop them anywhere and make sure they are in the same directory.
The test case simulates merging several xml files together, but in the test case, the merged files to be merged contain the same data, rather than different.
You have to tell the test case how many times to merge. On my linux box, it is about 350. On my OS X box, it is about 150. Below those numbers, the error is not present.
e.g.
ruby merge.rb 350
I really appreciate the help getting this resolved. I played around with gdb and this error yesterday, but did not come up with anything helpful. My C chops are, err.. poor.

Can you post your code?
