PATCH: PR ld/14862: Assertion fault in binutils-2.23.51.0.5/bfd/elf-strtab.c:247


Hi,

I checked in this patch to remove ref_dynamic_nonweak added by accident:

http://sourceware.org/ml/binutils-cvs/2012-10/msg00164.html

which contains:

http://sourceware.org/cgi-bin/cvsweb.cgi/src/bfd/elf-bfd.h.diff?cvsroot=src&r1=1.348&r2=1.349
http://sourceware.org/cgi-bin/cvsweb.cgi/src/bfd/elflink.c.diff?cvsroot=src&r1=1.455&r2=1.456

without ChangeLog entries.
