elisp: Checking Whether to Stop
17.2.14.1 Checking Whether to Stop
..................................
Whenever Edebug is entered, it needs to save and restore certain data
before even deciding whether to make trace information or stop the
program.
• ‘max-lisp-eval-depth’ and ‘max-specpdl-size’ are both increased to
reduce Edebug’s impact on the stack. You could, however, still run
out of stack space when using Edebug.
• The state of keyboard macro execution is saved and restored. While
Edebug is active, ‘executing-kbd-macro’ is bound to ‘nil’ unless
‘edebug-continue-kbd-macro’ is non-‘nil’.
