tagdust segfaults when output files exists already.
It crashes in the free_read_structure(param->read_structure) call for read_structure->numseq_in_segment[0]:

Thanks for reporting! I am currently re-writing tagdust to make it more robust and to include read/writing to compressed files.

tagdust seems like a great tool. I was looking for a program like this for many years. To to something similar with cutadapt seems to be quite difficult (although they should have most of the basic building block implemented).

For this specific project I wanted to extract a UMI-like 17bp sequence from the FASTQ file. when using -3 R:NNNNNNNNNNNNNNNNN the extracted reads are not all 17bp (rest of the read is useless). It would be nice if it would be possible to specify the exact read length is this case (and ignore reads that didn't match). I easily can do a simple post filter to fix it manually now.
When using -3 F:NNNNNNNNNNNNNNNNN with no R: specified, tagdust segfaults.
