I don't know yet what causes the linker to crash, but I found a work-around: If I download any pandoc version, extract it and run `stack build` inside that directory, it is fine. So I created a symlink to that local pandoc dir inside my package root and made pandoc a part of my own package. Then everything builds all right. Hence there must be something going wrong when stack downloads and builds pandoc somewhere inside .stack-work/. 
It seems difficult to just run the last sub-command as Niklas suggests, because after the crash all the temporary files of the failed build are gone. But I'll keep investigating, thanks for the suggestions!
