[Bug c++/23045] New: ICE in force_decl_die, at dwarf2out.c:12621

[dank at kegel dot com]

In testing gcc-4.1-20050716 for i686:

I originally ran into the following error

  internal compiler error: tree check: expected tree that contains 'decl
minimal' structure, have 'record_type'  in lookup_decl_die, at dwarf2out.c:5461

on the last line of a program.  While starting to come up with
a minimal test case, I was surprised to find that although
I could reproduce that error with preprocessed source,
stripping out the lines starting with # produced a different error:

x.ii: In instantiation of '__gnu_cxx::rope<char, std::allocator<char> >':
x.ii:42429:   instantiated from here
x.ii:41107: internal compiler error: in force_decl_die, at dwarf2out.c:12621

This is probably fortunate, since it now dies much sooner than at the
end of the program.  

To reproduce this, unpack http://kegel.com/gcc/ice-rope.ii.gz,
then compile it with

i686-unknown-linux-gnu-gcc -g -Wall -Werror -funsigned-char -c

Apologies for not finding a small testcase,
and for using a week-old snapshot for testing.
Hopefully this is useful anyway.

lookup_decl_die is most likely PR 22034.
force_decl_die is most likely PR 22514.

Yep.  

Compiling PR22034's testcase yields
pr22034.cc:6: internal compiler error: tree check: expected tree that contains
'decl minimal' structure, have 'record_type'  in lookup_decl_die, at
dwarf2out.c:5461

And compiling pr22514's testcase yields
pr22514.cc:11: error: expected unqualified-id before '}' token
pr22514.cc: In instantiation of 's::list<1>':
pr22514.cc:12:   instantiated from here
pr22514.cc:8: internal compiler error: in force_decl_die, at dwarf2out.c:12621

So this is a dup.  Sorry for the noise.

And sure enough, gcc-4.1-20050806 fixes it.
