            Bug ID: 15852
           Summary: strdup(NULL) causes SEGV
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: arno at cs dot vu.nl
                CC: drepper.fsp at gmail dot com

There is no checking of the input value, 2.18 just does:

size_t len = strlen (s) + 1;

as its first line. Is this correct / by design?

Thanks,
    Arno

--- Comment #1 from Andreas Jaeger <aj at suse dot de> ---
Yes, this is expected behaviour. strdup requires a valid pointer - and NULL is
not a valid allocated pointer.
