Subject: 26.2; CEDET/Semantic - Semantic constantly entering debugger with
 scheme
Date: Sat, 6 Jul 2019 12:45:20 +0100

Semantic enters the debugger whenever it's parsing invalid scheme code with
matching parentheses. The error code is "A Rule must return a single
tag-line list!"

To trigger this simply write
(define )

with electric matching pair mode active, the ending parenthesis is
automatically put and semantic constantly tries to enter the debugger,
making it unusable.
