Thanks for interesting hypothesis, but that's not the issue.
innocent though collected objects are living in D array MyClass[]
which are living in assoc array as value.
i checked attributes for GC block holding this array:
```
FINALIZE NO_SCAN NO_MOVE APPENDABLE NO_INTERIOR
```
I really doubting about NO_INTERIOR. can anybody confirm me that
is's working with array slicing which i heavily use?
also i found that block size is quite small
<pre>
array: [100A2FD00, 100A2F700, 100A33B80,
100A33500, 100A3FE80, 100A3F980, 100A3F400, 100A72600, 100A7DF80,
100A7DA80, 100A7D500]
array ptr: 100A72580 root: 100A72580:128 attr: FINALIZE NO_SCAN
NO_MOVE APPENDABLE NO_INTERIOR
[100985A00] keys: [1] as: 1 au: 100A2FD00
[100985A00] keys: [1] as: 1 au: 100A2F700
[100985A00] keys: [1] as: 1 au: 100A33B80
</pre>
array holds 11 64bit pointers but it's block size is only 128
bytes < 11 * 64 = 704 bytes. what's wrong with this arithmetics?
