LAME 3.96 alpha 2 (John33's 02/02 compile from rarewares) crashes when encoding at low bitrates.
I have tested 32, 40, 48, 56, 64, 80 and 96. All of these crash except, for some reason, 64.
This happens whether encoding abr or cbr with the following command lines:
lame.exe --abr n
lame.exe --preset n
lame.exe -b n
lame.exe --preset cbr n
From 112 upwards there doesn't seem to be any problem.
