I have reapplied this patch from last year;

https://sourceware.org/ml/gdb-patches/2014-05/msg00480.html

This fix was lost when the change that added the gdb.cp/var-tag.exp 
testcase was reverted and then restored again a few months ago.  In the 
restored version of the testcase, there were 12 FAILs fixed by this 
patch, rather than 9 as previously reported in the original version:

FAIL: gdb.cp/var-tag.exp: before start: c++: ptype E
FAIL: gdb.cp/var-tag.exp: before start: c++: ptype ee
FAIL: gdb.cp/var-tag.exp: before start: c++: ptype EE
