Fifth instance of the same shape, in readSV8:
const auto length = static_cast<double>(frameCount) * 1000.0 / d->sampleRate;
d->length = static_cast<int>(length + 0.5);
d->bitrate = static_cast<int>(static_cast<double>(streamLength) * 8.0 / length + 0.5);
frameCount is sampleFrames minus begSilence, both read from the file, so
the millisecond figure can land outside int:
taglib/mpc/mpcproperties.cpp:244:39: runtime error: 4.18294e+17 is
outside the range of representable values of type 'int'
The bitrate on the next line goes the same way when length is small, so
it is guarded too. One report before, none after, and the .mpc files in
tests/data report identical properties.
Turned up independently from two different seed files, sv8_header.mpc
and zerodiv.mpc.
