950 Mb for a 50 Mb is a lot of memory, even for Perl. How are you storing your file? As an array of characters? Then the memory consumption is no surprise. But if you store the file as a single string, you should consume about 50 Mb of memory.

I'd first try to find out what is causing the memory consumption. It might not even be related to your input. Something of the form $a [[1]] = 1; could cause the out of memory problem as well.
