Hi,
I've flicked through the 42 unique arm64 failures and given them a
first-step triage. The majority of issues look to be source based and
more than a few can be blamed on the move to C++14. Two of these I don't
understand (qutecom_2.2.1+dfsg1-5.2ubuntu2, sitplus_1.0.3-4.1build1). The
VLC one is strange, and I don't know how it has ever managed to build!
I generated my set of arm64 failures as so:
grep xenial-arm64 00list | cut -f 1 -d " " | sed "s@^@http://people.canonical.com/~doko/tmp/gcc6-regr/@" | xargs wget
gunzip *.gz
Triage notes follow...
Hope this helps, if it is useless, let me know what would be a better way
for me to help out with the AArch64 stuff.
Thanks,
James

I used "grep -v GPG" to remove error lines that looked like:
W: GPG error: http://ppa.launchpad.net xenial InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 1E9377A2BA9EF27F
This also removed two packages from my list that had system/package
failures:
gnuais_0.3.3-3
[ Package dependency not met ]

I used "grep -v "debian\/rules" to remove error lines that looked like:

This removed eight packages from my list which had system/environment
issues, ran out of memory, or failed a symbol match check.

-Wnarrowing
This is a mismatch between signed values and arm64's unsigned char. This
hits 21 packages. A typical failure looks like:

{-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,0,1,2,3,4,5,6,7,8,-1,-1,-1,-1,-1,-1,-1};
