[boost] Linking Problems starting with Boost 1.81

[Dennis Luehring via Boost]

1.79 links with my software
1.80 links with my software
1.81 does not link
1.82 does not link
1.83 does not link

Linux up to date Suse/Tumbleweed gcc 13.2.1

./bootstrap.sh
./b2 -j16 --toolset=gcc cxxflags=-fPIC --build-dir=./_build
address-model=64 architecture=x86 threading=multi --stagedir=./lib64-gcc
--build-type=complete --layout=versioned --without-mpi

these are the errors on linking when using 1.81 and above

anyone got an idea what changed between 1.80 and 1.81 to let my linking
fail with the above errors
the expression_parser_lib and expression_validation is my own code

Have you made sure to remove all prior builds of your code? I've
gotten errors on windows systems with MSVC when I did not clear out
old builds (in my case the object resulting from the precompiled
header was polluted with stuff from the old version of boost).

freshly build of boost, in different folders, fresh build with cmake
config etc., with complete delete of the build folder - definitly not a
problem

Looks like this is being worked on, judging from
