I'm reporting this as "important" because the failure rate is low compared with other packages which FTBFS randomly, but as upstream, I would really worry about the kind of error shown: The difference [...] is 35.999996185302734, which exceeds 1e-3 I would say this should never happen, but of course I know nothing about the program internals. Follows my standard template for FTBFS bugs: -------------------------------------------------------------------------- Dear maintainer: During a rebuild of all packages in unstable, this package failed to build. Below you will find the last part of the build log (probably the most relevant part, but not necessarily). If required, the full build log is available here: https://people.debian.org/~sanvila/build-logs/202606/ About the archive rebuild: The build was made on virtual machines from AWS, using sbuild and a reduced chroot with only build-essential packages. If you cannot reproduce the bug please contact me privately, as I am willing to provide ssh access to a virtual machine where the bug is fully reproducible. Caveat: The above should be understood as "where the reported randomness happens". If this is really a bug in one of the build-depends, please use reassign and add an affects on src:nanoflann, so that this is still visible in the BTS web page for this package. Thanks. -------------------------------------------------------------------------------- [...] test 2 Start 2: unit_tests_run 2: Test command: /<<PKGBUILDDIR>>/obj-x86_64-linux-gnu/tests/unit_tests 2: Working Directory: /<<PKGBUILDDIR>>/obj-x86_64-linux-gnu/tests 2: Test timeout computed to be: 10000000 2: [==========] Running 16 tests from 1 test suite. 2: [----------] Global test environment set-up. 2: [----------] 16 tests from kdtree 2: [ RUN ] kdtree.L1_vs_bruteforce 2: [ OK ] kdtree.L1_vs_bruteforce (765 ms) 2: [ RUN ] kdtree.L1_vs_bruteforce_rknn 2: ./tests/test_main.cpp:291: Failure 2: The difference between it->first and out_dists_sqr[i] is 35.999996185302734, which exceeds 1e-3, where 2: it->first evaluates to 2.1019476964872256e-44, 2: out_dists_sqr[i] evaluates to 35.999996185302734, and 2: 1e-3 evaluates to 0.001. 2: For: numToSearch=19 out_dists_sqr[i]=35.999996185302734 2: 2: 2: unknown file: Failure 2: C++ exception with description "map::at" thrown in the test body. 2: 2: [ FAILED ] kdtree.L1_vs_bruteforce_rknn (454 ms) 2: [ RUN ] kdtree.L2_vs_L2_simple 2: [ OK ] kdtree.L2_vs_L2_simple (0 ms) 2: [ RUN ] kdtree.robust_empty_tree 2: [ OK ] kdtree.robust_empty_tree (0 ms) 2: [ RUN ] kdtree.L2_vs_bruteforce 2: [ OK ] kdtree.L2_vs_bruteforce (765 ms) 2: [ RUN ] kdtree.box_L2_vs_bruteforce 2: [ OK ] kdtree.box_L2_vs_bruteforce (53 ms) 2: [ RUN ] kdtree.L2_vs_bruteforce_rknn 2: [ OK ] kdtree.L2_vs_bruteforce_rknn (335 ms) 2: [ RUN ] kdtree.SO3_vs_bruteforce 2: [ OK ] kdtree.SO3_vs_bruteforce (0 ms) 2: [ RUN ] kdtree.SO2_vs_bruteforce 2: [ OK ] kdtree.SO2_vs_bruteforce (0 ms) 2: [ RUN ] kdtree.L2_dynamic_vs_bruteforce 2: [ OK ] kdtree.L2_dynamic_vs_bruteforce (0 ms) 2: [ RUN ] kdtree.robust_nonempty_tree 2: [ OK ] kdtree.robust_nonempty_tree (0 ms) 2: [ RUN ] kdtree.add_and_remove_points 2: [ OK ] kdtree.add_and_remove_points (0 ms) 2: [ RUN ] kdtree.L2_concurrent_build_vs_bruteforce 2: [ OK ] kdtree.L2_concurrent_build_vs_bruteforce (2 ms) 2: [ RUN ] kdtree.L2_concurrent_build_vs_L2 2: [ OK ] kdtree.L2_concurrent_build_vs_L2 (3 ms) 2: [ RUN ] kdtree.L2_static_vs_dynamic 2: [ OK ] kdtree.L2_static_vs_dynamic (0 ms) 2: [ RUN ] kdtree.same_points 2: [ OK ] kdtree.same_points (0 ms) 2: [----------] 16 tests from kdtree (2385 ms total) 2: 2: [----------] Global test environment tear-down 2: [==========] 16 tests from 1 test suite ran.
