By the way, if you want a minimal example that should work try something
like:
using std;
using Moses;
MmapAllocator<int> alloc("test.mmap");
vector<int, MmapAllocator<int> > v(alloc);
for(unsigned i = 0; i < 10000; i++) {
v.resize(i + 1);
v[i] = i;
}
Then take a look at the test.mmap file. Should be a sequence of packed
integers.
Best,
Marcin
