Opus crash on MSVC 2013.3/2013.4

build.cmd

:: Reproducer for what seems to be a bug in MSVC 2013.3/2013.4.
::
:: The crash triggers when built with /fp:fast (http://msdn.microsoft.com/en-us/library/e7s85ffb.aspx)
:: and -Oi (http://msdn.microsoft.com/en-us/library/f99tchzc.aspx).
::
:: The compiler seems to compile the sqrt assignment loop in
:: https://git.xiph.org/?p=opus.git;a=blob;f=src/analysis.c;h=2ee853376a3e13ddcb1ffaed64f549bf858477bb;hb=HEAD#l497
:: into a series of SIMD operations, one of them being 'sqrtps'.
:: However, the output address of the generated sqrtps instruction
:: is not aligned on a 16-byte boundary. This is what causes the crash.
::
:: Drop this file (build.cmd) into the root of the Opus source
:: tree and run build.cmd.
::
:: (Make sure your command prompt is in the MSVC environment first,
:: by doing: call "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\vcvarsall.bat" x64)
