Description

I think one of the recent commits to nfd or ndn-cxx introduced a problem. At least, test cases are now consistently failing on all platforms:

[Exception] - memory access violation at address: 0x00001050: no mapping at fault address
 == [File] - ../tests/daemon/table/name-tree.t.cpp
 == [Line] - 278

What do you mean "consistently failing on all platforms"? How did it get past CI?

One possible sequence is:

NFD passes CI
ndn-cxx Change that breaks NFD is merged

#1948 would eliminate this problem.

Junxiao, the issue is introduced by recently merged commits in ndn-cxx and/or NFD (I believe it is due to ndn-cxx commit, but I don't have proof). You authored both recent commits, so please take a look.

@Davide. Unfortunately, we don't have yet #1948 in place and merges in the library can have unexpected effects to other projects and are not yet capturable by CI.

I can't reproduce this error on TravisCI https://travis-ci.org/yoursunny/ndn-cxx-breaks/jobs/52217073 or Jenkins http://jenkins.named-data.net/job/NFD/2572/.

If it needs a specific environment or configure line, please update Description (not Notes) to include that information.

Apparently, it is a trivial problem in TableNameTree test suite. The issue is that with XML output we are requesting all log output. One of the test cases used BOOST_CHECK_MESSAGE in the following way:

BOOST_CHECK_MESSAGE(m_names.empty(), "excess Names including " << *m_names.begin());

When verbose log output is not enabled, nothing bad is happening (the message printed only when case fails). When verbose log is enabled, then the test case fails as we are attempting to dereference invalid iterator.
