Subject: [Bug c++/30895] New: [4.1/4.2/4.3 regression] ICE with complex values in template parameter
Date: Tue, 20 Feb 2007 21:03:00 -0000 [thread overview]
Message-ID: <bug-30895-1771@http.gcc.gnu.org/bugzilla/> (raw)
The following code snippet triggers an ICE since GCC 3.4.0:
=====================================
template<int> struct A {};
template<typename T> struct B
{
A<T(0i)> a1;
A<T(0i)> a2;
};
=====================================
bug.cc:6: internal compiler error: in cp_tree_equal, at cp/tree.c:1858
Please submit a full bug report, [etc.]
Before we got the message:
bug.cc:5: sorry, unimplemented: `complex_cst' not supported by dump_expr
bug.cc:5: sorry, unimplemented: `complex_cst' not supported by dump_expr
bug.cc:6: sorry, unimplemented: `complex_cst' not supported by dump_expr
bug.cc:6: sorry, unimplemented: `complex_cst' not supported by dump_expr
I'm not quite sure whether the code is valid or not.
It does compile with "0.0" instead of "0i".
So if we consider complex types as basic arithmetic types,
the code should be valid IMHO.
OTOH, we don't allow casts from complex int to int.
But if we don't instantiate B this shouldn't matter IMHO.
