Summary: assertion failed in layer 2 decoding

Initial Comment:
LAME 3.99 (beta 0, May 14 2011)

While reconverting MP2 radio streams from a DVB-S radio station current lame seg faults with:
Assertion failed: idx <= x, file layer2.c, line 112
(layer2.c rev. 1.31)

The TS stream was demuxed with ProjectX and the audio stream processed with lame. lame-3.98 recodes the file with no errors.

Example file available at http://www.ddcd.de/lame.mp2

Message:
The 3.98 version is probably a stable release version, which has no
debugging code enabled. That's why it doesn't abort while decoding your
file. The layer2 stream has some invalid value, which results in an out of
bounds array access in some lookup table.
