Bug #: 14402
Summary: incorrect "self" for child class of nested class in
template class
Product: clang
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal

reduction of problem to simple test case
The attached file causes the following error:
----
/home/ryan/test.cpp:20:16: error: call to non-static member function 'm' of 'A'
from nested type 'C'
void x() { m(); }
^
1 error generated.
----
GCC does not generate this error and I don't believe it to be correct. The
problem can be worked around by calling '(*this).m()' instead of 'm()'.
Without knowing the internals of clang and having slept through my compilers
class (which led to some odd dreams), my three-miles-high assumption is that
the compiler is not properly realizing that it is inside of a child class.
By commenting out the 'template<typename T>' at the top of the definition of
class A, the error does not appear (although you will also have to uncomment
the relevant portions in main()).
I tested the problem on clang 3.1-8 and then compiled from trunk and also
reproduced the behavior there.
It is possible I misunderstood the C++ language spec and this is actually
intended behavior, but that doesn't seem quite right to me.
