Bug#554852: [dpkg-dev] Please blacklist end@Base

[Peter Fritzsche]

Package: dpkg-dev
Version: 1.15.4.1
Severity: wishlist

When compiling with binutils-gold a new symbol with the name end@Base is
added. It is currently unknown why it gets added and a request to get more
information about it was send to #553435 and forwarded to
http://sourceware.org/bugzilla/show_bug.cgi?id=10876

Could you consider to add this symbol to the blacklist file?

The initial idea to do so came Raphael Hertzog <hertzog@...> from
http://lists.debian.org/debian-devel/2009/11/msg00249.html


Test output with binutils-gold:
$ objdump -w -f -p -T -R /usr/lib/libxyz.so.0.0.0|grep 'end$'
00000000000108d8 g    D  *ABS*  0000000000000000  Base        end
00000000000108d8 g    D  *ABS*  0000000000000000  Base        _end

and with old binutils
$ objdump -w -f -p -T -R /usr/lib/libxyz.so.0.0.0|grep 'end$'
000000000020f860 g    D  *ABS*  0000000000000000  Base        _end
