FLAC crashing on Windows

added Platform::Windows desktop Severity::normal Type::bug Version::master git + 1 deleted label

changed milestone to %2.2.1

I get this problem too

From my tests:

Files encoded with FLAC 1.2.1 crash if encoded with -8 parameter. Files encoded with FLAC 1.3.1 crash if encoded with -7 or -8 parameter.

Flac.exe -8 input.wav

The output FLAC files have no tags at all.

It crashes in lpc_restore_signal_16_intrin_sse2 in libflac.

Program received signal SIGSEGV, Segmentation fault.
