    Problem Report Number 2339
    Submitter's Classification Test Suite problem
    State Resolved
    Resolution Test Suite Deficiency (TSD)
    Problem Resolution ID TSD.X.1205
    Raised 2004-02-24 05:04
    Updated 2004-03-02 16:49
    Published 2004-03-02 16:49
    Product Standard Internationalised System Calls and Libraries Extended V3 (UNIX 03)
    Certification Program The Open Brand certification program
    Test Suite VSRT version 5.2.5
    Test Identification rt.os/ioprim/ftruncate test2
    Specification Base Definitions Issue 6
    Location in Spec none
    Problem Summary line optimized out by compiler
    Problem Text in ftruncate.c line 236


    int *iaddr;

    and lines 344,345

    if (sigsetjmp(env,1) == 0)
    i = *iaddr;

    because i is never used again, optimizing compilers will remove lines
    344 and 345. Need to add volatile to line 236

    volatile int *iaddr;
    Test Output
    ************************************************************************
    /tset/rt.os/ioprim/ftruncate/T.ftruncate 2 Failed

    Test Description:
    If _POSIX_SHARED_MEMORY_OBJECTS and _POSIX_MEMORY_PROTECTION are
    defined or the implementation supports the ftruncate() function as
    defined in System Interfaces and Headers, Issue 5:
    On a call to ftruncate() when fildes refers to a shared memory
    object and the effect of the call is to decrease the size of the
    shared memory object and whole pages beyond the new end were
    previously mapped, the whole pages beyond the new end shall be
    discarded and subsequent references to them shall result in
    generation of a SIGBUS signal.

    Test Information:
    Did not get SIGBUS
