UBSAN identified a problem at exit time by gcc-8 only #174

Closed jeking3 closed 5 years ago

During a build of Boost.Rational with UBSAN and gcc-8 - this issue is reproducible in https://github.com/boostorg/rational/pull/30.

jeking3 commented 5 years ago

Re-ran with clang-6, gcc-7, and gcc-8 and only the gcc-8 UBSAN triggers this failure. https://travis-ci.org/boostorg/rational/builds/448008702

raffienficiaud commented 5 years ago

I think I know why we have this UB, but the fix is far from easy (has again something to do with global variables init order). I am afraid I will not be able to fix this anytime soon, certainly not for 1.69

jeking3 commented 5 years ago

Another case: https://travis-ci.org/boostorg/rational/jobs/450100503

raffienficiaud commented 5 years ago

Hi, I have a potential fix on this branch: topic/GH-174-undefined-behaviour-on-exit. Would it be possible for you to try UBsan on this one? I do not know how to set it up with the build, would you please point me to something that integrates UBsan with boost.build?

Thanks!

jeking3 commented 5 years ago

If you have gcc-7 or gcc-8 available you can run UBSAN yourself like this:

$ UBSAN_OPTIONS=print_stacktrace=1 ../../../b2 cxxflags=-fno-omit-frame-pointer cxxflags=-fsanitize=undefined cxxflags=-fno-sanitize-recover=undefined linkflags=-fsanitize=undefined linkflags=-fno-sanitize-recover=undefined linkflags=-fuse-ld=gold variant=debug

This is pretty much what the Travis CI build jobs in boost-ci do. In any case I will start up a CI build from that branch with my CI changes on top.

Here's the UBSAN CI job:

https://travis-ci.org/jeking3/test/jobs/453094905

jeking3 commented 5 years ago

Given the relative size of boost::test runs, the standard boost-ci template will beed to be trimmed. We cannot run all the language levels for example.

When you have something else to test let me know and I can run it again with a reduced set of build matrices that might actually complete. If we get it all working I will submit a PR into Boost.Test.

Thanks for checking this. The branch I am pointing to you is green on my CI (gcc5 c++03/c++11, apple clang Xcode 8 c++03/c++11 and VS 2008,12,13 and 17). I do not have any sanitizer activated because I do not know how to set this up :) I will follow your command line soonish.

From the logs https://travis-ci.org/jeking3/test/jobs/453094905, I can see very strange things:

====== BEGIN OUTPUT ======
../../boost/test/impl/unit_test_log.ipp:451:134: runtime error: member call on address 0x7fff9c276b00 which does not point to an object of type 'lazy_ostream'
0x7fff9c276b00: note: object is of type 'boost::unit_test::lazy_ostream_impl<boost::unit_test::lazy_ostream, boost::unit_test::basic_cstring<char const>, boost::unit_test::basic_cstring<char const> const&>'
 b0 7f 00 00  e0 ec 40 00 00 00 00 00  00 c1 40 00 00 00 00 00  70 51 41 00 00 00 00 00  c0 6a 27 9c

while the definition is class lazy_ostream_impl : public lazy_ostream and the access raising the error is a ref on lazy_ostream. So I do not understand.

There are also other things about the exceptions that are not being caught by boost.test and which I do not understand neither:

I am not running the tests in the example folder, which explains why I am not seeing the VS errors. I am also activating all the warnings as errors for the library but not for the tests themselves (too much work to fix them all), which may explain why you have so many failures. The warnings should be silenced by specific headers for the library itself, problem is that compilers may have different set of warnings that are not covered. This is a recent change,

Something like

/usr/include/c++/8/bits/stl_tree.h:452:21: error: static assertion failed: comparison object must be invocable with two arguments of key type
       static_assert(__is_invocable<_Compare&, const _Key&, const _Key&>{},
                     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

is I believe a compiler issue, see https://github.com/boostorg/test/issues/152 .

Do you have other tests environment where the UBsan issue was visible? Otherwise I will configure/run it on my side when I have time.

I ran the change through CI and I did not see the issues I originally reported, so I would say the issue was resolved by the changes.
