    Problem Text
    The tests in the string test area assume that the host system is
    ASCII-based but there is nothing in ANSI or POSIX that requires this
    to be so. Several test programs use the fact that in ASCII, turning
    on the high-order bit of a byte containing a printable character
    changes the value of the byte. This is not always true for EBCDIC
    charcters - the value may stay the same [('a' | 0xf0) == 0xf0 in
    EBCDIC]. Tests that assume the state of any bit (including the
    high-order bit) of any character are not valid. The following tests
    are failing because they assume they can turn on the high-order bit to
    change the value of a printable character:
    ANSI.os/string/Mstrchr/T.strchr 2,
    ANSI.os/string/Mstrcmp/T.strcmp 1,
    ANSI.os/string/Mstrcmp/T.strcmp 3,
    ANSI.os/string/Mstrrchr/T.strrchr 2,
    ANSI.os/string/strchr/T.strchr 2,
    ANSI.os/string/strcmp/T.strcmp 1,
    ANSI.os/string/strcmp/T.strcmp 3,
    ANSI.os/string/strncmp/T.strncmp 1,
    ANSI.os/string/strncmp/T.strncmp 3,
    ANSI.os/string/strpbrk/T.strpbrk 2,
    ANSI.os/string/strrchr/T.strrchr 2,
    ANSI.os/string/strspn/T.strspn 1,
    ANSI.os/string/strspn/T.strspn 2,
    ANSI.os/string/strtok/T.strtok 1, and
    ANSI.os/string/strtok/T.strtok 2.
    Test Output
    /tset/ANSI.os/string/strchr/T.strchr 2 Failed
    Test Description:
    strchr() returns a null pointer if character c does not occur in
    string s.
    Test Strategy:
    VERIFY NULL return when character is not in the string.
    Test Information:
    strchr did not return expected value
    pointer & value of first argument : 0x37320f0
    \360\360\360a\360\360\360\247a\360\360\360\247\360\360a\360\360\
    247
    value of second argument : \247
    expected return value : 0x0
    actual return value : 0x37320f7
