Bug#355909: g++-4.0: Internal compiler error in instantiate_decl, at cp/pt.c:11539

[Roland Levillain <roland@lrde.epita.fr>]

Package: g++-4.0
Version: 4.0.2-10
Severity: normal

g++-4.0 (version 4.0.2-10) dies with an ICE on this (invalid) piece of
code:


template <typename T>
struct foo
{
  static const int i;
};

template <typename T>
const int foo<float>::i = 42;

int
main ()
{
  return foo<float>::i;
}


~ % g++ g++-4.0.3-ice.cc
g++-4.0.3-ice.cc: In function 'int main()':
g++-4.0.3-ice.cc:13:   instantiated from 'const int foo<float>::i'
g++-4.0.3-ice.cc:13:   instantiated from here
g++-4.0.3-ice.cc:13: internal compiler error: in instantiate_decl, at cp/pt.c:11539

(Same result with -O1, -O2 and -O3.)

g++-2.95, g++-3.3 and g++-3.4 don't exhibit an internal compiler error
-- they all exit with a (valid) error message.
