[vlc-devel] Build Errors on i420_yuy2.c

[황종범]

Hi,

Upon building "vlc" from the git, I've got the following errors on
"i420_yuy2.c".

Here are what I did.
1. ./bootstrap
2. Change the optimization option from "-O2" to "-O0" in "./configure" for
debugging. (There are 7 places of "-O2" changed to "-O0")
3. ./configure --enable-debug --disable-optimizations
4. ./make

The above procedure had been working OK until the VLC dated 2012/10/10.

Note that if I don't change the optimization option, there are NO errors.
But the debugger complains "SEGABT".

Any Idea?

Thanks.

James Hwang
