[Bug c++/27309] New: [4.0/4.1/4.2 regression] ICE on invalid constructor definition

[reichelt at gcc dot gnu dot org]

The following invalid testcase causes an ICE since GCC 4.0.0:

=================================
struct A
{
    int i;
    A() i() {}  // missing colon
};

struct B
{
    A a;
};

B b;
=================================

bug.cc:4: error: expected ';' before 'i'
bug.cc:5: error: expected `;' before '}' token
bug.cc:12: internal compiler error: vector VEC(tree,base) index domain error,
in locate_ctor at cp/method.c:885
Please submit a full bug report, [etc.]

Btw, the code also caused GCC 2.95.x and 3.0.x to crash.

Mark, do you want to add some of the testcases from PR27379 and PR27380
to the testsuite as their mode of failure is a little bit different
although the underlying problem seems to be the same?

There's certainly no harm in that, but I don't think we'll increase
coverage in any interesting way; the underlying cause really was the
same for all of those failures.
