assertion failed: ClassBType.info not yet assigned when using -opt:l:inline and Spark 2.4.0 on Scala 2.12 #11247
Description
Hello,
We are maintaining the open source project https://github.com/twitter/algebird, and try to upgrade algebird-spark module to new spark version 2.4.0 and scala version 2.12.7 (https://github.com/twitter/algebird/tree/apanasenko/spark_2.4.0). But we are hit a problem (works fine on 2.11.12):

To reproduce results, you need to do:
$ git clone git@github.com:twitter/algebird.git
$ cd algebird/
$ git checkout apanasenko/spark_2.4.0
$ ./sbt -212 ";project algebird-spark; compile"
a problem reprdocible even if I delete all code in algebird-spark module and keep only one file with:
class AlgebirdRDD[T](val rdd: RDD[T])
