[librecat-dev] Error when processing the same file twice

[Patrick Hochstenbach]

Hello Georg

I can’t repeat the error on my machine with a simplified version of your script. I use Catmandu 1.09 and Catmandu::MARC 1.231.

Can you run the ‘test.pl’ script in the attachement and see if you sill get the errors you report?

I try to first do a MARC to JSON conversion to get some data out of a MARC input file (which in the end will go into a MongoDB) and then the same input file should be processed again in order to output an enriched MARC file. I can run one or the other but when I try to process both I get an error
