>Description:
had the file of a big size (2G byte over) can read.
It is not division that tests everything though the problem doesn't occur at present in my environment.
I greement of cd9660 to the standard is not investigated. However, I thought that there is especially no problem because it is only reading.
I changed to the source of 6.1 release.
