[Bug c++/17248] New: __always_inline__ throws "unimplemented" in -O0 mode

[wyderski at ii dot uni dot wroc dot pl]

The C++ compiler fails when the -O0 optimization
mode and a method has the __always_inline__ attribute
specified. The command line used was:

gpp -O0 -c allocator.cpp -I./ -save temps

The version string:

Reading specs from c:/djgpp/bin/../lib/gcc/djgpp/3.41/specs
Configured with: /Build/gcc34/gnu/gcc-3.41/configure djgpp
--prefix=/dev/env/DJDIR --disable-nls --disable-libstdcxx-pch
Thread model: single
gcc version 3.4.1

It displays the following message:

./base/list.h: In destructor `base::list<traits>::~list() [with traits =
base::simple_list<mdl::expression_base*, 
false>::aux_simple_traits<mdl::expression_base*,  false>]':
