Error description

  • Memory fault / segmentation fault / signal 11 on zLinux s390x
    when calling isopen
    The build for CISAM 7.26.FC2 fails on zLinux s390x O/S.  When
    trying to run the demo programs they fail in the function at
    lisopen.  It appears the product has not been built correctly.
    Consider the following simple piece of code:
    ---------------testisam.c------------------------
    #include <isam.h>
    main()
    {
         int     dk;
         printf( "before isopen()\n" );
         isopen("perform", ISAUTOLOCK + ISOUTPUT);
         printf( "after  isopen(): %d\n", dk );
    }
    ---------------testisam.c------------------------
    when compiled and run ..
    --------------compisam.sh----------------
    gcc testisam.c -DMlinuxz -D_BSD_SOURCE -D_LARGEFILE64_SOURCE -o
    testisam.exe  -I$INFORMIXDIR/include -L$INFORMIXDIR/lib
    -lifisam -lifisamx
    --------------compisam.sh----------------
    $ sh compisam.sh
    $ ./testisam.exe
    before isopen()
    Memory fault
    $
