Comment (by Kamedo2):
I tried the input.mp4 and it crashed on Win7 64bit, Core i7 870. I tried
to use the foobar2000 decoded wav as an input, but it also fails. I tried
many diverse wav files and quiet speech samples seem to cause the crash
problem. I'm going to post another problematic sample that crash the vo-
aacenc. I compressed the file into FLAC, but using the original wav
doesn't help.
