panic: conflict with wildcard route

[blinkinglight]

how can i do this? by url path len
router.GET("/:b/:a", func(c *gin.Context) {
c.String(500, "1")
})
router.GET("/:c/:b/:a", func(c *gin.Context) {
c.String(500, "2")
})
router.GET("/:d/:c/:b/:a", func(c *gin.Context) {
c.String(500, "3")
})

It should be an issue at https://github.com/julienschmidt/httprouter, since Gin uses that router.
