Frequency command causes allocated memory exhausted message on csv file with many fields

[excel4]

xsv is a great utility - thanks much for creating this very useful program!

Attached is a csv file with 333 fields. The frequency command works before indexing the file. However, after indexing, the frequency command immediately reports many "allocated memory exhausted" error messages.

FYI, the stats and count commands works fine after indexing. I have not tried many of the commands so I don't know if other commands also fail.

I am running xsv version 0.13.0 on Windows 10:
[xsv-0.13.0-x86_64-pc-windows-gnu.zip]gnu.zip)

all_100k.csv

Just to clarify - this issue only happens with index, right?

You can try if the new fork qsv fixed the issue, as here the development has stalled. Other alternatives include miller and csvtk, but those, albeit still fast, don't use index.
