[CWB] cwb-scan-corpus

[Simon Meier-Vieracker]

Hi Stefan,

I get the following error:

Error: non-integer offset in key '?pos+0!=/\$\./'.

I think I have version v3.4.13, at least the README file tells me something about v3.4.13. How can I check which version I really do have installed?

Best, Simon
