hstr: malloc: attempt to free non-allocated memory (uninitialized/freed pointer/NULL)

Whenever I use hstr I get the following errors:

$ hstr
ls
hstr(45522,0x1142ce5c0) malloc: *** error for object 0x7fccffe4f40f: pointer being freed was not allocated
hstr(45522,0x1142ce5c0) malloc: *** set a breakpoint in malloc_error_break to debug
[1]    45522 abort      hstr
$ ls

It doesn’t matter if I trigger it with hstr, hh or ^R, I always get the malloc errors. hstr still works, but always prints the errors I recently re-installed my machine from scratch but the problem persists.

My config:

macOS Mojave v10.14.5
zsh 5.7.1 (x86_64-apple-darwin18.2.0)

alias hh=hstr                                # hh to be alias for hstr
export HISTFILE=~/.zhistory                  # ensure history file visibility
export HISTFILESIZE=100000                   # increase history file size
export HISTSIZE=${HISTFILESIZE}
export HSTR_CONFIG=hicolor,raw-history-view,blacklist
bindkey -s "\C-r" "\eqhstr\n"                # bind hh to Ctrl-r

😞 thank you@jonand. I will set up macOS installation when I will be releasing my other project and try to debug it there. Thanks for patience & help!
