[Bug 1817048] [NEW] apt/trusty: Stack overflow in apt-ftparchive; on arm64, breaking about a third of the tests

[Julian Andres Klode]

Public bug reported:

[Impact]
autopkgtest suite on arm64 is basically useless, as about a third of the tests do not work, because they rely on apt-ftparchive generating an archive

[Test case]
Substantially less tests should fail, there should be no segfaults.

[Regression potential]
I am cherry-picking a fix that changes statically length arrays (that are too small) to vector. A possible regression could be fields missing I guess, it should definitely be easily noticeable. Low risk.
