Error description
In either ISPF or if you use IPCS via batch, the VERBX DFHPD750 'PG=3' command results in a Abend SA78-X'10'. The dump shows: module BLSRVEC3 offset X'191D6': Abend SA78-X'10'. This is due to CICS module DFHPGDUF doing a "double FREEMAIN" of its EP_LIST_TOKEN.

Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: Abend in DFHPGDUF when processing * * 'PG=3' or 'PG' keywords. * **************************************************************** A CICS 6.2 user enters " IPCS VERBX DFHPD750 'PG=3' " or " IPCS VERBX DFHPD750 'PG' " and sees an ABENDA78 - 10 abend due to the dump formatter issuing two STORAGE(RELEASE) calls, specifying the same ep_list_token.
