Migration issue from mysql to postgresql using pgloader

Question

While migrating from MySql to PostgreSQL it giving error- INFO: Control stack guard page unprotected Control stack guard page temporarily disabled: proceed with caution

pgloader mysql://root:root@localhost/opdb1 postgresql://postgres:root@localhost:5432/opdb
2019-11-04T11:40:48.116000Z LOG Migrating from #<MYSQL-CONNECTION mysql://root@localhost:3306/opdb1 {1009DAE7F3}

KABOOM! INFO: Control stack guard page unprotected Control stack guard page
  temporarily disabled: proceed with caution

What I am doing here?

Control stack exhausted (no more space for function call frames). This is probably due to heavily nested or infinitely recursive function calls, or a tail call that SBCL cannot or has not optimized away.

PROCEED WITH CAUTION.
