Boost does not work properly on modern macOS, for example 10.11, with Intel C++ Compiler. When compiling with default language/standard/compatibility flags, select_compiler_config.hpp picks up intel.hpp which does not define BOOST_NO_RTTI...

We're running cycle_ratio_example.cpp in the tests, but it uses a non-deterministic random number generator which very occasionally results in the assertions failing. It's not clear if this is inevitable, or...

examples crash when run

The following two examples crash at runtime: astar_maze.cpp kevin-bacon2.cpp Sorry but I don't see what the issue is off hand.

Title says it all, msvc runtime checks catch this.

In order to get us green again, I've disabled 2 tests in test_autodiff_8.cpp for Clang/MacOS: https://github.com/boostorg/math/blob/a243640baddfaa318859d622fddb7abc3ba8a978/test/test_autodiff_8.cpp#L12 and https://github.com/boostorg/math/blob/a243640baddfaa318859d622fddb7abc3ba8a978/test/test_autodiff_8.cpp#L135 One for @pulver.

Experiment with C++20 modules.

OK folks, here's a bit of an experiment with C++ modules, it works with msvc but gcc leads to a fairly hopeless spiral of internal compiler errors :( There are...
