> Hi development community,
> 
> I do have a volkszaehler on a RPI running which is reading 2 out of 3 
> EMH electricity meters already for almost 12 month without a problem. 
> The headache is coming from the third meter which is also a EMH from the 
> same generation (i). The only difference is that the 2 working once are 
> from my electriciy provider and the third one is a my own (bought from 
> comet).

> The problematic meter causes an immidiate segmentation fault crash of 
> the vzlogger. I did double check that by moving the IR head from the 
> working meter(running already for days) over to the non working one 
> which immidaitly crashes the vzlogger. I did work already with Udo and 
> it seemed to be a problem with the parser in the vzlogger in combination 
> with the output of this specific meter.
