           Summary: Any SocketException causes program to segfault
           Product: D
           Version: 2.012
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P2
         Component: Phobos
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: d brian.codekitchen.net


strerror_r is incorrectly defined in std.c.string to return a (const char *),
but in fact it returns an int (probably an error from when strerror was
switched out for the threadsafe strerror_r). In linux/GDC builds
SocketException calls strlen() with the return value of strerror_r, causing a
segfault.

Looks like I oversimplified the problem -- see man page for strerror_r at
http://linux.die.net/man/3/strerror_r

There are two incompatible versions of strerror_r, the POSIX standard one
returns an int and always stores the error string in the supplied buffer. The
GNU specific version behaves as Phobos currently assumes, returning a char *
and maybe-or-not using the supplied buffer.

The POSIX standard behavior is available in GNU through a #define macro. Note
that other platforms such as OS X only support the POSIX version, so I'd argue
that for portability the POSIX version should be used in Phobos, or the
differences should be abstracted in the D code.

This was fixed almost two years ago.
