Hi, I performed a git bisect compiling[1] both readline and bc from upstream[0] and found the commit (8e6ccd0) that introduced the issue. However this commit is the entire diff from "readline-7.0 patch 5" to "readline-8.0 distribution sources and documentation".
I also found that if I compiled without readline or libedit support the behaviour reverted to normal, albeit without any readline history.
