looks like a problem with the compiler-macro for MAKE-INSTANCE.
SB-PCL::MAKE-INSTANCE->CONSTRUCTOR-CALL uses the initargs to build a function name, so second call looks up that name in the environment, then breaks when VOLATILE-INFO-LOOKUP tries to compare the circular list in the names with EQUAL.
looks like it was inherited from cmucl in version 0.7.10.31 or so
