[Bug libc/11100] New: sysdeps/unix/sysv/linux/ptrace.c PTRACE_SETOPTIONS inappropriate pointer check

["chris2k01 at hotmail dot com" <sourceware-bugzilla at sourceware dot org>]

In sysdeps/unix/sysv/linux/ptrace.c, on line 102, if __BOUNDED__POINTERS__ is 
true, checks are done that pointers point at appropriate locations. Such a 
check is done on the "data" argument to ptrace() if the "request" argument is 
PTRACE_SETOPTIONS. However, according to ptrace(2) (and, indeed, according to 
the gdb sources and the kernel sources), the PTRACE_SETOPTIONS request accepts 
a bitmask of PTRACE_O_* values as its "data" argument, *not* a pointer.
