Reduced:
import core.stdc.stdio;
import core.memory;
void main()
{
printf("1: %lld\n", cast(ulong)GC.stats.usedSize);
void* z = GC.malloc(100);
printf("2: %lld\n", cast(ulong)GC.stats.usedSize);
GC.free(z);
printf("3: %lld\n", cast(ulong)GC.stats.usedSize);
GC.collect();
printf("4: %lld\n", cast(ulong)GC.stats.usedSize);
}
shows:
1: 16
2: 144
3: 16
4: 4096
