Thanks for attending to this.
"Unfortunately" I am not longer able to recreate the problem in Quartus 18.1.0 Build 625 09/12/2018 SJ Lite Edition, so for some reason my Quartus installation handles the construction now. The problem was originally described in:
where Quartus made the error:
"Internal Error: Sub-system: BPM, File: /quartus/db/bpm/bpm_hard_block_util.cpp, Line: 3458 ... Quartus Prime Information ... Version: 18.1.0 Build: 625 Edition: Lite Edition"
Back when I initially looked into the problem I could recreate the error several times, and it only occurred when the special construction was enabled.
But I have attached the the project that originally caused the problem anyway, in the file "SO_52622535_FF_by_concurrent_assign__Intel.zip".
I consider this issue closed, unless I encounter the problem again.
