    Problem Report Number 1077
    Submitter's Classification Test Suite problem
    State Resolved
    Resolution Test Suite Deficiency (TSD)
    Problem Resolution ID TSD.X.0533
    Raised 1970-01-01 08:00
    Updated 2003-03-13 08:00
    Published 1998-12-22 08:00
    Product Standard Internationalised System Calls and Libraries Extended V2 (UNIX 98)
    Certification Program The Open Brand certification program
    Test Suite VSRT version 5.0.2
    Test Identification rt.os/procprim/execl 2
    Problem Summary TSD4R.00007 These tests fail if the address the memory segment mapped in the parent process happens to be a valid address in the child process.
    Problem Text
    This request applies to:

    rt.os/procprim/execl/T.execl 2 Failed
    rt.os/procprim/execle/T.execle 2 Failed
    rt.os/procprim/execlp/T.execlp 2 Failed
    rt.os/procprim/execv/T.execv 2 Failed
    rt.os/procprim/execve/T.execve 2 Failed
    rt.os/procprim/execvp/T.execvp 2 Failed

    In each of these test a process uses mmap(2) to map some memory into its
    address space. A child process is then fork(2)ed and a new process image
    created using one of the above exec functions. The expectation of the
    test is that mmap(2)ed memory is released in the child process due to the
    action of the exec(2). This is verified by reading from the mapped memory
    address and checking that the read caused a SIGSEGV or SIGBUS signal to
    be sent to the child process.

    These tests fail because the address the memory segment
    is mapped to in the parent process happens to be a valid address in the
    child process. This was verifed using adb. If the test address is set to
    0x0 the expected SIGSEGV is indeed seen.
