Bug#865660: diffoscope uses 35GB ram for comparing influxdb_1.1.1+dfsg1-4_arm64.changes

Package: diffoscope

I noticed that a diffoscope running on jenkins.debian.net would consume
79G of virtual memory and 35G of resident memory while comparing
influxdb_1.1.1+dfsg1-4_arm64.changes after about 25 cpu minutes. Given
that the largest package from influxdb is ~10M, we're seeing a 3000 times
memory use. That's bad.

Unfortunately, I cannot provide any more details at this point. Sorry.
If this turns out to be undebuggable, please just close the report.
