[Bug c++/18835] New: memory consumption is high for C++ testcase

[pinskia at gcc dot gnu dot org]

The testcase in PR 14719 shows that we use a large amount of memory still even on the mainline.

I was just compiling at -O0, 380M seems high to me for this "simple" C++ testcase (yes it is 8000 lines 
but most of that is comming in from boost's headers so the testcase itself is much smaller).

I should note that the compile time is not that bad at about 40s but that is still high for -O0.

------- Comment #3 from hubicka at gcc dot gnu dot org  2009-02-23 16:39 -------
Testcase no longer compile:
/home/jh/bitmachine.cc:5049: error: declaration of 'typedef typename
Context::inner_context_type::state_base_type
boost::fsm::simple_state<MostDerived, Context, Reactions, InnerInitial,

Can we have updated one?
