package.el generates a runtime error

[ghost]

Hello. When running esup an error is generated:

ERROR: the child emacs had the following errors:
  ERROR(profile-sexp) at /Applications/Emacs.app/Contents/Resources/lisp/emacs-lisp/package.elc:15: (error Not enough arguments for format string)

Results will be incomplete due to errors.

My init.el begins as:

(require 'package)
(add-to-list 'package-archives
             '("melpa" . "https://melpa.org/packages/") t)
(package-initialize)

I'm running a nightly version of Emacs: 26.0.50 from 6-11 from emacsforosx.com. I'll retest on 25.2.

Turns out that the error is a red-herring. It was a bug in the actual profiling code. I had an extra format call.

The bug is fixed in a589005. Melpa will have a new release in a few hours. Please reopen if this doesn't fix your bug.

I got the same error running esup on a custom file.

ERROR: the child emacs had the following errors:
  ERROR(profile-sexp) at /usr/local/Cellar/emacs-mac/emacs-26.3-z-mac-7.8/share/emacs/26.3/lisp/calendar/calendar.elc:50 with sexp (byte-code

Running esup without prefix works fine. One of the files I am calling (which contains additional init information) is not profiled in detail so I wanted to give it a look and then the error happened.

This portion of the esup report is what I wanted to further profile:
