Investigate Zstandard decompression error
make test-network with current tor
HEAD yields a number of warning related to Zstandard decompression, which indicates we have a bug somewhere. The relevant error snippet is:
Warning: Error while uncompresing data: bad input? Number: 2 Warning: Zstandard decompression didn't finish: Unknown frame descriptor. Number: 2
Both Nick and I are able to reproduce this issue on FC and Debian stretch with different versions of libzstd, which probably indicate that this issue is in our code.
