Description:
With the recent update of the package to version 0.17-53 it stopped working for me, hanging in an infinite loop without any output.

I checked and the only major related haskell package version upgrade is haskell-network, but it's version bumped to 3.1.1.1 and all pandoc-citeproc build-dep requires is <3.2, so that should not be a problem. Maybe a simple rebuild will fix it? Manually compiling from the github repo produced a working version for me.
This task depends upon

Unfortunately the update to 0.17-54 did not fix it.
I tried reproducing this on another system, but was unable to do so and reinstalling all of pandoc did not help either. The only significant difference between the two systems that I can think of is, that the one it is not working on has only a single CPU.

Running `pandoc-cite -y test.bib`, where test.bib is the attached simple bibtex file, spawns 4 thread processes, of which only one runs occassionally (see the attached htop screenshot). Maybe it somehow locks itself up? Although I can't explain how the package changes introduced that, since pandoc-citeproc itself has not changed since mid-February.

Can anyone else with a single CPU reproduce?

I tried on my VPS with a single CPU but cannot reproduce:

Indeed it seems to be fixed with one of the updates. Sorry for not updating this, I was done with the project I used pandoc for.
