[Bug c++/42820] New: ICE in tree-check, accessed elt 2 of tree_vec with 1 elts in tsubst, at cp/pt.c:9868
The following code causes the error:
internal compiler error: tree check: accessed elt 2 of tree_vec with 1 elts in
tsubst, at cp/pt.c:9868
(I am using the debian gcc-snapshot 20100117)
It compiles fine with g++-4.4. I have seen similar bug reports in bugzilla, but
they are all marked either as fixed or as not-a-regression, so I am adding this
here, sorry if this is a duplicate.

[Bug libstdc++/42819] [C++0x] std::async fails to compile with simple tests, including N3000 example
--- Comment #1 from paolo dot carlini at oracle dot com 2010-01-21 10:28
---
Jon, what's going on, here? I'm referring first of all to the version without
lambdas, so:
#include future
int work2(int value);
void work(int value)
{
auto handle = std::async(work2, value);
}
As far as I can see, the problem is with the typename _Fn::result_type used in
the return type, which obviously work2 lacks. Looks like there is a defect in
the N3000 draft.

--- Comment #5 from jwakely dot gcc at gmail dot com 2010-01-21 10:42 --- (In reply to comment #2) Yes, it's a defect (a concepts hangover) - the example is invalid according to the async spec. I pointed it out to Lawrence and he's dealing with it for the next draft. To expand on this: std::async is defined in terms of Fn::result_type, assuming that Concepts would provide Callable::result_type, so the example would be valid. Without concepts, that doesn't work, so the example is invalid. The most likely fix will be to use result_ofFn(Args...)::type instead, making the example valid again. I chose to follow the spec, not the example which appears in a non-normative note. (In reply to comment #4) Well, using result_of / decltype would make it more usable in the meanwhile, should not be a big deal, right? Yes, I think we could do that. I'll ask Lawrence how he's planning to address it - we might as well do that way. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42819

We seem to test for this feature in gcc.dg/builtin-object-size-6.c
struct D
{
int i;
struct D1
{
char b;
char a[10];
} j;
};
void
__attribute__ ((noinline))
test6 (struct D *d)
{
if (__builtin_object_size (d-j.a[3], 0) != (size_t) -1)
abort ();
if (__builtin_object_size (d-j.a[3], 1) != sizeof (d-j.a) - 3)
abort ();
if (__builtin_object_size (d-j.a[3], 2) != 0)
abort ();
if (__builtin_object_size (d-j.a[3], 3) != sizeof (d-j.a) - 3)
abort ();
}
But this is confused by for example changing the testcase to
struct X {
void *p;
struct Y {
char s[4];
} y;
};
void * __attribute__((noinline,noclone))
myalloc (unsigned int sz)
{
return __builtin_malloc (sz);
}
int main()
{
struct X *p = myalloc (sizeof (struct X)
+ sizeof (Hello World) + 1 - sizeof (p-y.s));
struct Y *q = p-y;
__builtin___strcpy_chk (q-s, Hello World,
__builtin_object_size (q-s, 1));
return 0;
}
where clearly nothing tells you that we allocate an object of type struct X
and the strcpy uses struct Y - still as we propagate around the pointers
we'll end up with exactly the same IL as before and miscompute the object size.
