------- Comment #5 from reichelt at gcc dot gnu dot org  2008-12-28 22:11 -------
Confirmed. Reduced testcase for comment #1:

=====================================================================
template<typename> struct A;

template<typename, template<typename> class = A> void foo();

void bar()
{
  foo<int>();
}
=====================================================================

bug.cc: In function 'void bar()':
bug.cc:1: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]


Removing the first template parameter yields a different error:

=====================================================================
template<typename> struct A;

template<template<typename> class = A> void foo();

void bar()
{
  foo();
}
=====================================================================

bug.cc: In function 'void bar()':
bug.cc:1: internal compiler error: in tsubst_decl, at cp/pt.c:7958
Please submit a full bug report, [etc.]
