[patch] Add two new C++ testcases

[Lee Millward]

Hi,

My patch for PR29022 actually fixed two other bugs as well (as pointed
out by Volker Reichelt in Bugzilla) - PR28740 and PR27316 however the
testcases from these bugs haven't been added to the testsuite.

The attached patch adds the testcases from these two bugs to the C++
testsuite, ok to apply? Any particular preference for the names of the
new tests?

Cheers,
Lee.
