You need to get your grep fixed. This is not a bug in PCRE or pcregrep. 
In my version of grep (on Gentoo Linux) it also works:

$ echo teST | pcregrep -i '\Qtest\E' 
teST
$ echo teST | grep -iP '\Qtest\E'
teST

My grep is GNU grep 2.5.4. I assume it's using the installed PCRE
library, which is 7.9. Check that you are using the latest releases of 
grep and the PCRE library. If you are, complain to the maintainers of 
grep. If not, try to update.
