           Summary: segfault in std.stdio.readln()
           Product: DGCC aka GDC
           Version: 0.24
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Phobos
        AssignedTo: dvdfrdmn users.sf.net
        ReportedBy: dlang davidb.org


The following program causes a segfault on EOF with gdc-0.24. I've
reproduced this on amd64, x86 both with the binary distribution and with
the gentoo emerged version (gcc-4.1.2). This does not appear to happen
with dmd.

======================================================================
module readline;

import std.stdio;

void main ()
{
  while (1) {
    char[] buf = readln ();
    if (buf is null)
      break;
    writef ("%s", buf);
  }
}
======================================================================

Upon EOF, there is a segfault inside of a string dup inside of readln:

uint std.stdio.readln(struct std.c.stdio._iobuf*, inout char[])










I can try to build phobos with debugging symbols if other are unable to
reproduce this problem.
