*** TEST RESULTS FOR COMMIT 327301a4604da40da264c554daa8c1e97aa2fbe2 ***

    OOM in setup_group
    
    We alloc, seek and read using section sizes in object files.  Fuzzed
    objects can have silly sizes, but that's OK if the system supports
    memory over-commit.  The read fails because we hit EOF and that
    usually results in a graceful exit.
    
    But if we memset before the read then the invalid size results in
    attempting to write to a huge number of memory pages, and an eventual
    Out Of Memory after probably swapping like crazy.  So don't memset.
    There really isn't a need to clear the section contents anyway.  All
    bytes are written with a good object file by the read and following
    loop converting section index in target order to ELF section header
    pointer, and the only untidy bytes are the 4 bytes past the group
    flags when pointers are 8 bytes.  Those don't matter but the patch
    clears them for anyone poking around in a debugger.  On error paths
    it's as good to free section contents as it is to clear them.
    
    Noticed when looking at PR4110 fourth test case.
    
            PR 4110
            * elf.c (setup_group): Don't clear entire section contents,
            just the padding after group flags.  Release alloc'd memory
            after a seek or read failure.
