Out of Memory Errors - Possible Enhancement

That is 437 MB more RAM than is being used by 3.34.1 x86.  I presume that you are using the same version (whatever that is, I asked but you haven't said) of SQLite3 on both Windows 7 and Windows 10?

I suppose it could also be due to differences in the heap memory manager in the subsystem runtime (MSVCRT.DLL) between the two OSes as well.
