#6427: Crash on any file - Windows build from git repository
-------------------------------------+-------------------------------------

-------------------------------------+-------------------------------------
Summary of the bug:
I built ffmpeg from the git repository at https://github.com/FFmpeg/FFmpeg
(last commit 220b24c7c97dc033ceab1510549f66d0e7b52ef1) with the current
MinGW from http://www.mingw.org. ffmpeg crashes at the start on any file.
The location of the error depends on the file but the problem function's
name seems to always contain _sse.
Compiler:
gcc 5.3.0
binutils 2.25.1
w32api 5.0
mingwrt 5.0
O/S: Windows 10 Version 1607
How to reproduce:
1. git clone https://github.com/FFmpeg/FFmpeg ffmpeg
2. mkdir ffmpeg-build
3. cd ffmpeg-build
4. ../ffmpeg/configure --prefix=/mingw/local --disable-w32threads
5. make && make install
6. Download https://samples.ffmpeg.org/testsuite/i263.avi
7. ffmpeg_g.exe -report -i i263.avi -y -r 24 -threads 1 test.mpg
