constexpr diagnostics test case #01


This is a test case that shows locality information for failed constant
expressions in a simple class hierarchy.

The test case is comprised of a base class with member data, and no constex=
pr
constructor.

The error is:

%$bin/H-x86_64-gcc-trunk.20101101/bin/g++ -g -std=3Dgnu++0x
constexpr-diagnostics-base1.cc
constexpr-diagnostics-base1.cc:18:19: error: the type =E2=80=98const derive=
d=E2=80=99 of
constexpr variable =E2=80=98obj=E2=80=99 is not literal

The error desired is:

%$bin/H-x86_64-gcc-trunk.20101101/bin/g++ -g -std=3Dgnu++0x
constexpr-diagnostics-base1.cc
constexpr-diagnostics-base1.cc:18:19: error: the type =E2=80=98const derive=

"constexpr"
