New submission from Robert Rohde <rohde at robertrohde.com>:
I attempted to use GZipFile to process a 1.93 GB file that expands to 18.8 GB.
This consistently produces the same corrupted output file that has approximately, but not exactly, the right output file size.
I bypassed GZipFile by calling the 7-Zip executable to open the compressed file. This works correctly and consistently.
I haven't tried to figure out how GZipFile works, but I assume that this failure is probably related to the very large size of the files I am working with. I've used GZipFile before on much smaller files with no apparent problems. I have no idea what precisely goes wrong, or how to fix it, but I felt it was important to note that GZipFile isn't working for at least some very large files.
