Subject: Stripping golang binaries causes crashes
Date: Wed, 17 Jul 2013 14:33:46 +0100
Package: golang
Version: 2:1.1.1-3
Usertags: origin-ubuntu saucy ubuntu-patch

Downstream bug:

golang binaries crash on some architectures if they are stripped during
packaging. Upstream are aware of this, but do not currently support the
stripping of binaries.

Dave Cheney says:

	* not supported, as in, we don't support it, and recommend against
	  it when asked
	* not tested, we don't test stripped binaries as part of the build
	  CI process
	* is often broken, stripping a go binary will produce anywhere
	  from no, to subtle, to outright execution failure, see above
	* doesn't do what you want, we have a flag called -g, but the
	  information it stores in the elf sections is a superset of what
	  strip thinks it is removing, in short, strip does not strip out
	  the debug data, we hide it too well.

	To clarify my previous statements.

	* I do not disagree with the debian policy, it is there for a good
	* Having said that, it stripping Go binaries doesn't work, and
	  nobody is looking at making it work, so there is that.

	Thanks for patching the build formula.

Debian policy says that binaries "should" be stripped, not "must" be
stripped, so I assumed that policy permits this, and that applying the
following patch would be the pragmatic thing to do for Ubuntu. I think
that doing anything else would be considerable effort. Please consider
the same for Debian.
