The following invalid code snippet is accepted by GCC since at least
GCC 2.95.3:
====================================
struct A
{
template<int> void foo() = 0;
};
====================================
A similar code snippet causes an ICE since GCC 4.0.0:
====================================
struct A
{
template<int> void foo() = 1;
};
====================================
bug.cc:3: internal compiler error: in grokfield, at cp/decl2.c:899
Please submit a full bug report, [etc.]
It was rejected before, but only because the pure specifier was malformed,
and not because it was present at all:
bug.cc:3: error: invalid initializer for virtual method `void A::foo()'
