    Test Identification /tset/CAPI.os/procenv/setrlimit/T.setrlimit{11}
    Specification Base Definitions Issue 6
    Location in Spec https://pubs.opengroup.org/onlinepubs/009695399/functions/setrlimit.html
    Problem Summary Our implementation fails to enforce the soft limit for malloc() for data
    segment size (RLIMIT_DATA).
    That is, a request for memory that exceeds rlim_cur may succeed.
    Problem Text In VSU tset/CAPI.os/procenv/setrlimit/, the second part of the test for
    Assertion 11 ("When data
    segment size exceeds the limit malloc() fails and sets errno to ENOMEM")
    fails because the
    malloc() call succeeds

    Note that there may be applications that rely on this behavior so we
    would prefer to fix it in the
    next release and provide plenty of warning.
