Currently the AAC pulse_data tool can try to apply pulses to offsets outside
of the boundaries of the spectral coefficients. This leads to a crash
(SIGSEGV) with a stream generated wit the following command:
zzuf -s16 -r0.001:0.1 -b1193- <
mpeg4audio-conformance/compressedMp4/al04_08.mp4 > fuzzed.mp4

Attached is a patch to clip pulse positioning to 1023.
