	..  the typename5.C failure has left :-) 

Nevertheless, programs I have that are heavily relying on templates still 
make the system run out of memory depending on the optimization level. I'm 
trying to narrow down the problem to a simple testcase, but :^( .. 

Anyway, this is a _severe_ limitation for large programs :-(. or even 
small programs... {:-((

For example, the following testcase quoted from "egcs-bugs/1997-Nov/0235.html" 
still crash at compile time with the current 971201-snapshot on my box:

// --- test.cc ---
#include <iostream.h>
#include <list>
#include <algorithm>
using namespace std;

int main()
{
    int daten [16] = { 1, 4, 4, 6, 1, 2, 2, 3, 6, 6, 6, 5, 7, 5, 4, 4};
    list<int> menge;
    copy (daten, daten+16, back_inserter(menge));

    return 0;
}
// --- cc.tset ---

$g++ -Wall -O test.cc 
test.cc: In function `int main()':
test.cc:10: virtual memory exhausted

This happens in the call to copy; this let's me wonder if this is not 
related to non-trivial template instantiations of functions arguments. 
That's my 0.00000000000000000000000000000000000000000002cts guess.

(Note that I use to (I have to) call the compiler with no warning flags 
for my programs, therefore there is in my case no warning/optimization flags 
combinations.) 



Anyhow, thanx a lot for the job !-) 

Best Regards, Max.
