SIGSEGV caused by libmp4v2.so.0

[Mark Sheppard]

I'm getting a crash when running mp4info on a particular file. It's 1.6 GiB so I won't attach it! But here's the callstack (as reported by gdb) showing that libmp4v2.so.0 passed a bad value to strcasecmp(3):

Program received signal SIGSEGV, Segmentation fault.
