Big thank.


Switch to /bin64 and now works until full memory using.

My guess is you are compiling to 32bit and the GC tries to 
reserve >4gb wich it can't, therefore out of memory


Compiling to 64bit with: `dmd -m64 -run test.d` works no problem

"Memory allocation failed" on big array

[urned utt via Digitalmars-d-learn]

Hello.

having about 6 Gb free RAM, trying to execute:

```d
string[] dic;

for (int i = 0; i < 100_000_000; i++)
{

dic ~= "just a word number "~to!string(i);

if (i%1_000_000 == 0)
{
		writef("processed line %s: %s\n", format("%,3d", i), 
format("%,3d", dic.length));

}
}

```

got an error:
"processed line 32,000,000: 32,000,001
core.exception.OutOfMemoryError@src\core\lifetime.d(126): Memory 
allocation failed"


app used is about 1.6 Gb, more than 4 stays free.

1. What is happened, why dynamic array have mem limit? For 
example, golang uses all free memory that it can.

2. How to fix this?
3. (optional) How to display memory usage? Cannot find function 
for this.


Thanks.
