Ah, it is a checking-only ICE. It ICEs during:
20115 #ifdef ENABLE_CHECKING
20116 /* Try to get a constant value for all non-type-dependent
expressions in
20117 order to expose bugs in *_dependent_expression_p and constexpr.
*/
20118 if (cxx_dialect >= cxx0x)
20119 maybe_constant_value (fold_non_dependent_expr_sfinae (expr,
tf_none));
20120 #endif
which in turn calls tsubst_decl on the verbose variable, while not called from
instantiate_decl of the containing function.
So local_specializations is NULL, retrieve_local_specialization does nothing
and
finally register_local_specialization segfaults, because it expects
local_specializations is non-NULL.
