Symptoms
DataPump import terminates with the following errors in the import log file:

ORA-39126: Worker unexpected fatal error in KUPW$WORKER.PUT_DDLS [TABLE_STATISTICS]
ORA-06502: PL/SQL: numeric or value error 
LPX-00225: end-element tag "HIST_GRAM_LIST_ITEM" does not match start-element tag "EPVALUE" 
ORA-06512: at "SYS.DBMS_SYS_ERROR"

Cause
The statistics included in the import may be malformed.

Solution
To workaround this issue, repeat either the expdp or the impdp using the parameter EXCLUDE=STATISTICS. 
After import, regather the statistics for the imported objects 
in the target database using the DBMS_STATS package.
