[Bug c++/34397] New: [4.3 regression] ICE on invalid default template parameter

[reichelt at gcc dot gnu dot org]

The following invalid code snippet triggers an ICE on mainline:

=================================================
template<typename T, int = T()[0]> struct A
{
  typedef A<T> B;
};
=================================================

bug.cc:3: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]

The code is accepted by GCC 4.2.x and older.

Well, I'm using the version from 2007-12-06, and since then nothing C++ related
has been checked in.

I can see the ICE since at least 2007-05-13 on mainline (I don't have any older
mainline versions around).

Pretty sure. I bootstrapped a really clean one ("svn diff --no-ignore" showed
nothing) last night on i686-pc-linux-gnu. It still shows the segfault.

The x86_64-unknown-linux-gnu compiler was bootstrapped without modifications
from a snapshot. It's a little older, though (2007-11-16).

For some reason it works correctly on i386-apple-darwin and powerpc-linux-gnu. 
I wonder if something is not miscompiling the C++ front-end.

No, I have build non-bootstrapped gcc with gcc-4.1 and it still shows the same
problem.  Adding a "debug_tree (t)" at the top of find_parameter_packs_r() in
cp/pt.c results in:

 <array_ref 0x2aaaadfef5a0
    arg 0 <cast_expr 0x2aaaae129c40
        type <template_type_parm 0x2aaaae1383c0 T type_0 type_6 VOID

constant invariant 0> arg 2 <integer_cst 0x2aaaae00b480 0>pr34397.cpp:3:
internal compiler error: Segmentation fault
<...>

The segfault now points to:

Program received signal SIGSEGV, Segmentation fault.
print_node (file=0x30d1948860, prefix=0x7fffc27c5510 "arg 3", node=0x17, 
    indent=4) at ../../gcc-svn/trunk/gcc/print-tree.c:197
197       code = TREE_CODE (node);

So, we can conclude that something is wrong with arg 3 of ARRAY_REF expr.
Perhaps it is left uninitialized?

Probably it is not OK to build ARRAY_REF expr using build_x_binary_op(). Could
a c++ expert check this usage in cp/pt.c, around line 10823?

I would expect pt.c to call grok_array_decl (which is the same function called
by the parser), not build_x_binary_op.

------- Comment #19 from paolo dot carlini at oracle dot com  2009-02-05 12:47 -------
Indeed, in my experiments the problem seems due to build_min_nt not passing
NULL_TREEs as called by build_x_binary_op. The patch I'm going to attach then
works, in the sense that the testcase compiles (and then an error is emitted in
case of instantiation).

I also tried calling directly grok_array_decl from tsubst_copy_and_build, and
indeed that largely works (but note that, for some reason, the grok_*
functions, called by the parser, are not called often in pt.c, many build_x_*
functions instead), but there are subtle issues, like sfinae7.C failing...

------- Comment #21 from mmitchel at gcc dot gnu dot org  2009-02-08 22:35 -------
Paolo --

My earlier suggestion to try grok_array_decl may indeed have been misguided. 
Some of the grok_* functions do more parser-style analysis than we want when
processing templates.  

In theory, the way this ought to work is that we parse for a while, until we
know what the user meant, and then call a function that actually generates
code.  When processing a template, we call that same underlying function after
substitution.  But, in practice, we may not always have organized things that
tidily.

In that case, the best fix is to factor out syntactic dismabiguation bits from
grok_array_decl, and make a new underlying function that is called from both
the parser and the template machinery.

[Bug c++/34397] [4.2/4.3/4.4 regression] ICE on invalid default template parameter

[paolo dot carlini at oracle dot com]

------- Comment #23 from paolo dot carlini at oracle dot com  2009-02-09 17:09 -------
Mark, can you have a closer look to the draft patch? I'm still looking but I
don't think we can extract and commonize much code from grok_array_decl, unless
we accept to pass from the callers an in_parser flag, or use a function
pointer, I can see only such rather ugly solutions...

You may well be right.  Your draft patch looks plausible.

Thanks,
