Same here with 9.6-pre (release_9.5.5-1096-gf83e45).

Like with:

    |  | 
    #+TBLFM: $1='(eval "\n")

IIUC, the command "echo 42" outputs a newline, newlines are not allowed
as in cell values.

So a workaround would be to trim the output:

    | 42 |
    #+TBLFM: $1='(string-trim (shell-command-to-string "echo 42"))


But, you should report it as a bug: org should raise an error, not enter
an infinite loop, generating an infinite amount of text.
