Emacs 30.0.91 aborts while reading a lisp integer with invalid read syntax from the M-: (eval-expression) minibuffer. I can't reproduce this with Emacs 29.4, which correctly shows an invalid read syntax error message in the minibuffer. [Steps to repoduce] 1. Do a clean checkout the latest emacs-30 git branch 2. Build a --with-pgtk and debug build options 3. Start `emacs -Q' under gdb 4. Type `M-:' then something with invalid read syntax like `#0400'.
