Package: binutils
Version: 2.16.1-3
I hit this segfault[1] when building d-i.
I rebuilt binutils unstripped, reproduced & collected a backtrace[2].
An obvious NULL-pointer dereference.
I don't know if the bug is that its just not checking the pointer before
accessing it, or if a NULL pointer should never have made it this far.
I did do some blackbox testing and determined that 3 of the -u
arguments[3] will cause a segfault whenever they are used alone. If I
remove these three args, gcc completes without error.

Changes:
binutils (2.16.1cvs20051109-1) unstable; urgency=low
.
* New upstream CVS snapshot.
* Fixes broken PLT handling on m68k. Closes: #327780
* Don't compile flex files with -Werror, fixing mips builds.
Closes: #333980
* Don't check undefined symbols introduced by "ld -u" for TLS. Closes:
#326103
.
* 117_mips_symbolic_link.dpatch: merged upstream - removed.
.
* debian/rules: pass --disable-werror on ia64 as current gcc generates
too many false positives. Closes: #336939
.
* 125_fix_tc_arm_cast.dpatch: new patch from Lennert Buytenhek to fix
cast warning and arm builds. Closes: #336175
.
* 121_i386_x86_64_biarch.dpatch: imported from Ubuntu at request of
Daniel Jacobwitz to fix biarch linking on i386/amd64. Closes:
#334626, #334673
.
* debian/rules: remove any reference to pkgstriptranslations - an
Ubuntu-ism that shouldn't have been in the Debian package in the first
place but that isn't needed in Ubuntu any more in any event.
.
* debian/rules: MAKEOVERRIDES is now clobbered by the top level
Makefile, so switch to overriding MAKE itself (sic) to pass the
customized VERSION variable/string down to sub-directories for
-multiarch and -hppa64 builds. Thanks to Daniel Silverstone for the
suggestion.
