#509 SIGSEGV when CALL program with RETURNING

[Xin Wang]

CALL program with RETURNING will cause SIGSEGV, e.g.:

foo.cob:

PROGRAM-ID. foo.

DATA DIVISION.
    WORKING-STORAGE SECTION.
        01  n PICTURE 9.

PROCEDURE DIVISION.

    CALL 'foo1' RETURNING n END-CALL

    DISPLAY n END-DISPLAY.

END PROGRAM foo.

foo1.cob:

PROGRAM-ID. foo1.

DATA DIVISION.
    LINKAGE SECTION.
        01  n PICTURE 9 VALUE ZERO.

PROCEDURE DIVISION RETURNING n.

END PROGRAM foo1.

Output:

% cobc -F -W -j -x foo.cob foo1.cob 

attempt to reference unallocated memory (signal SIGSEGV)
abnormal termination - file contents may be incorrect

Tested in 2.2 and 3.0-dev.0 (r2530).
