Linking Problems starting with Boost 1.81

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
