The following invalid testcase triggers an ICE since gcc 4.0.0:
===============================
struct A
{
static void foo() = 0;
};
===============================
The error message is:
bug.cc:3: internal compiler error: in grokfield, at cp/decl2.c:899
Please submit a full bug report, [etc.]
The respective code from cp/decl2.c reads:
/* Initializers for functions are rejected early in the parser.
If we get here, it must be a pure specifier for a method. */
gcc_assert (TREE_CODE (TREE_TYPE (value)) == METHOD_TYPE);
gcc_assert (error_operand_p (init) || integer_zerop (init));
DECL_PURE_VIRTUAL_P (value) = 1;
Apparently the first assert is triggered - we have a FUNCTION_TYPE
instead of a METHOD_TYPE in this example. This was probably broken by
Giovanni's patch for PR17401.
