Description of problem:
The ^ operator is not working correctly when used after a | operator.

Version-Release number of selected component (if applicable): vim-common-7.4.640-4.fc22.x86_64

How reproducible: Always


Steps to Reproduce:
1. Create a file and add the contents below:
Hello
World

2. Open the file in vim
3. Enter "/^Hello\|^World"

Actual results:
Only the Hello line matches

Expected results:
Both lines match.

Additional info:
The expected behavior was present in vim-common-7.4.475-2.fc20 so a bisect may help narrow down the issue.

This issue is not present in Vim compiled from source with

$ export LDFLAGS="-Wl,-z,relro -fstack-protector -rdynamic -Wl,-export-dynamic -Wl,--enable-new-dtags -L/usr/local/lib -Wl,--as-needed -L/usr/lib64/perl5/CORE -lperl -lresolv -lnsl -ldl -lcrypt -lutil -lpthread -lc -lm -lnsl -lselinux -lncurses"

$ export CFLAGS="-O2 -g -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -m64 -mtune=generic -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -D_FORTIFY_SOURCE=2"

$ ./configure --prefix='/tmp/vim/dist/' --enable-pythoninterp=dynamic --enable-rubyinterp=dynamic --enable-cscope --enable-multibyte --with-features=huge --with-tlib=ncurses --disable-tclinterp --enable-netbeans --disable-gui

The compiled version is pretty close to the packaged version in terms of flags and such.  The major difference is Perl is enabled in the packaged version (I couldn't figure out how to get those working); and clientserver, clipboard, X11, xfontset, xterm_clipboard, xsmp_interact are enabled with the configuration above.

My suspicion is that perhaps the issue is lurking on one of the patches carried with the package.
