If the "GC.collect()" line is commented out, it works somehow.
Please help me understand why this is happening. This is a very reduced
Try to compile in debug mode, maybe you breach some contract.

Thank you for the reduced test case.
A small change to the test

First, here's a reduced version:

On my machine its a "realloc(): invalid pointer".
From what does the allocator know, that `p' is somehow an array?
This causes a segfault when run with rdmd -gx:
void main()

import std.experimental.allocator : allocatorObject,
expandArray;

std.experimental.allocator.building_blocks.allocator_list :
AllocatorList;
import std.experimental.allocator.building_blocks.region :
Region;
