In reviewing the test matrix: https://www.boost.org/development/tests/develop/developer/serialization.html I'm getting the following error message when on a couple of my tests:

Looks like a minor snafu in ../boost/math/ccmath/isnan.hpp ... or not. Could someone who understands math/special functions took a look into this? On a totally separate note: I'm getting another failure on the same matrix: Test output: teeks99-dkr-dc6-17 - serialization - test_dll_simple / clang-linux-6.0~c++17 Rev 1c12b5c15fc82f0cb6d4bd931a057fc050df8a34 / Sun, 29 Oct 2023 21:39:02 +0000 Lib [2023-10-29 23:34:28 UTC]: fail See boost/bin.v2/libs/serialization/test/clang-linux-6.0~c++17/debug/debug-symbols-off/threading-multi/visibility-hidden where the links points to a file containing:

So .... This parts builds a dll/shared library which is used in the test. There doesn't seem to be anything wrong with this. Does anyone have any ideas? Robert Ramey
