Dosbox-x handling of data files with large amount of rows.

[stef-1988]

Hi, is there any conf setting we can try to stop dosbox-x crashing when re-indexing a file that contains over 300,000 rows?
We've done some testing and it can handle files that are bigger in size that contain less rows.
So far we've tried upping the cpu type to pentium4 and have added in memsize=64 but still crashes.
