Subject:	bug with grep 3.0.2 in cygwin 3.0.7
MIME-Version:	1.0

Hi, 
I encounter some problem with grep option -E on cygwin 3.0.7 


echo "a^b" | grep "a^b" #answer a^b ie it's OK 
but 
echo "a^b" | grep -E "a^b" #answer nothing " for me it's KO 


I have to backslash ^ to be OK like : grep -E 'a\^b' 


Is-it a bug ? 
I don't know if all versions of cygwin and grep are concerned. 


My cygcheck is OK with: 

Windows 10 Professional Ver 10.0 Build 18362 


Running under WOW64 on AMD64
