            Bug ID: 28525
           Summary: glob segfaults when arg pglob->gl_lstat is NULL
           Product: glibc
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: glob
          Assignee: unassigned at sourceware dot org
          Reporter: spk121 at yahoo dot com
  Target Milestone: ---

Hello. I was using glob and created a segfault by leaving the pglob->gl_lstat
argument NULL improperly.
Posix does say that "It is the caller's responsibility to create the structure
pointed to by pglob." So segfault *is* a valid response.
But since your implementation does set errno and return for some error cases
not explicitly called out in POSIX, perhaps a null check and errno response
could be a good enhancement.
Thanks.
