LEN is the number of elements
in FIELDS minus one, or put another way, it is the maximum subscript
used in FIELDS.
and its code does
for (i = 0; i < len; i++)
{
layout_type (TREE_TYPE (fields[i]));
DECL_FIELD_CONTEXT (fields[i]) = type;
TREE_CHAIN (fields[i]) = fields[i+1];
}
DECL_FIELD_CONTEXT (fields[i]) = type;
DECL_CLASS_CONTEXT (fields[i]) = type;
thus expecting the final ones to be fields[4], not fields[5] (which is
the actual size from 0, not the last field member)

* libgcc2.c (L_eh): Define __eh_pc.
Replace __eh_type with generic pointer __eh_info.
Fri Oct 31 01:47:57 1997 Jason Merrill <jason@yorick.cygnus.com>
Support for nested exceptions.
* tinfo2.cc (__is_pointer): New fn.
* exception.cc (struct cp_eh_info): Define.
(__cp_exception_info, __uncatch_exception): New fns.
(__cp_push_exception, __cp_pop_exception): New fns.
* except.c: Lose saved_throw_{type,value,cleanup,in_catch}.
Lose empty_fndecl.
(init_exception_processing): Likewise. __eh_pc is now external.
(push_eh_info): New fn.
(get_eh_{info,value,type,caught}): New fns.
(push_eh_cleanup): Just call __cp_pop_exception.
(expand_start_catch_block): Use push_eh_info. Start the eh region
sooner.
(expand_end_eh_spec): Use push_eh_info.
(expand_throw): Call __cp_push_exception to set up the exception info.
Just pass the destructor or 0 as the cleanup. Call __uncatch_exception
when we rethrow.
(expand_builtin_throw): Don't refer to empty_fndecl.
