Bug#518927: Please update dtoa.c in all packages that use it
 
Package: general
Severity: normal

Hi,

many source packages contain the "dtoa.c" file that bears the following
copyright notice:

* The author of this software is David M. Gay.
*
* Copyright (c) 1991, 2000, 2001 by Lucent Technologies.

All these packages will be miscompiled by gcc-4.4, because dtoa.c
violates strict aliasing rules. See more details at
http://patrakov.blogspot.com/2009/03/dont-use-old-dtoac.html

Please do a whole-archive search for source files (you'll mostly find
copies of dtoa.c, gdtoa.c and various internal headers) that contain the
string "#define word1(x) ((U*)&x)->L[0]", and clone this bug
accordingly.

System information: irrelevant.

Diego Elio Pettenò: you received this mail because I want you to do the
same thing for Gentoo.
