[Bug c++/27666] New: [4.0/4.1/4.2 regression] ICE with volatile in conditional expression

["reichelt at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The following code snippet triggers an ICE since GCC 3.0
(it disappeared in 3.3.[2-6]):

=======================================
struct A
{
    A(int);
};

void foo(volatile A a) { 1 ? a : 0; }
=======================================

bug.cc: In function 'void foo(A)':
bug.cc:6: error: no matching function for call to 'A::A(volatile A)'
bug.cc:3: note: candidates are: A::A(int)
bug.cc:2: note:                 A::A(const A&)
bug.cc:6: error:   initializing temporary from result of 'A::A(int)'
bug.cc:6: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in build_conditional_expr, at cp/call.c:3326
Please submit a full bug report, [etc.]

I'm not sure whether the error message before the ICE is correct
or whether the code is in fact valid.
