I was using clang, 
export CC="clang"
before I did anything.

although it is a clang but I think, the latest ffmpeg just crash this
compiler. I will post the crash log below.

and I found if I revert the commit, 
00ab9cdae1a96dfea33cd505076a83823f390aa4
jpeglsdec: Prevent out of array write.

clang did not crash anymore.

but when linking, this error
--------
Undefined symbols for architecture x86_64:
  "_ff_librtmp_protocol", referenced from:
      _av_register_all in libavformat.a(allformats.o)
ld: symbol(s) not found for architecture x86_64
--------
occurs.

then I tried to use gcc as the compiler.
export CC="gcc-4.2 -m64"
the same link error occurs.


Appe. the crash log of clang.
