************** JIT 디버깅 **************
JIT(Just In Time) 디버깅을 사용하려면 이 응용 프로그램 또는 컴퓨터의
config 파일(machine.config)의 jitDebugging 값을
system.windows.forms 섹션에 설정해야 합니다.
또한 응용 프로그램은 디버깅할 수 있도록 컴파일되어야
합니다.

예:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

JIT 디버깅을 사용하면 처리되지 않은 모든 예외는
이 대화 상자에서 처리되지 않고 컴퓨터에 등록된 JIT

because there is '$'s instead of '\$'s in $if$ statement.
so it can be fixed by change '$' to '\$'.
it's not an engine problem, just a rule file problem.
