Environment: zsh.

After launching lem some times, terminal was broken.

Normal case:

$  ros install cxxxr/lem
Installing from github cxxxr/lem
To load "lem":
  Load 1 ASDF system:
    lem
; Loading "lem"
......
[1/3] System 'lem' found. Loading the system..
[2/3] Processing build-hook..
[3/3] Attempting to install the scripts in roswell/ subdirectory of the system...
Found 4 scripts: lem lem-ncurses-ccl lem-ncurses lem-rpc
/Users/keno/.roswell/bin/lem
/Users/keno/.roswell/bin/lem-ncurses-ccl
/Users/keno/.roswell/bin/lem-ncurses
/Users/keno/.roswell/bin/lem-rpc

After lem:

$  ros install cxxxr/lem
Installing from github cxxxr/lem
                                To load "lem":
                                                Load 1 ASDF system:
