Guardian Procedure Calls Reference Manual

The element_ptr parameter is not a multiple of 16.
These values are defined in kpool64.h for C and KPOOL64 for pTAL. Other results indicate an
error within the pool structure, probably corruption. Two such results may indicate a programming
error with respect to the element specified by element_ptr: POOL64_POOLTAGMISMATCH
usually implies the program has written beyond the allocated element; POOL64_BADHEADER
often results if the element has already been freed.
