Re: conflict between Crypto++ 5.6.0 and GNU binutils 2.19.91.20091014-0ubuntu1
Cool, it looks like the the bug has been fixed in GAS. Hopefully that will get into the Ubuntu release, or into an update shortly after. Let me know if I still need to do anything. -- From: Zooko O'Whielacronx zoo...@gmail.com Sent: Tuesday, October 27, 2009 7:22 PM To: Crypto++ Users cryptopp-users@googlegroups.com Subject: Re: conflict between Crypto++ 5.6.0 and GNU binutils 2.19.91.20091014-0ubuntu1 Matthias Klose from the Debian and Ubuntu projects has identified which exactly patch to GNU assembler causes the problem: http://sourceware.org/bugzilla/show_bug.cgi?id=10856 --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Crypto++ Users Google Group.

Re: conflict between Crypto++ 5.6.0 and GNU binutils 2.19.91.20091014-0ubuntu1
The error is clearly occurring within the SHA256 inline assembly code. But I have no idea what the (fairly large) binutil patch is doing. How can we find out who submitted the the binutil patch and contact him or her? I can also look at this in the debugger and see if I can fix it in Crypto++ code. Can you either give me a shell account on a machine that can reproduce this, or tell me how to reproduce this, starting with a blank VMware instance? Until this is fixed, you can try to work around it by disabling the SHA256 (or all) assembly code. -- From: Zooko O'Whielacronx zoo...@gmail.com Sent: Tuesday, October 27, 2009 8:21 AM To: Wei Dai wei...@weidai.com Subject: Re: conflict between Crypto++ 5.6.0 and GNU binutils 2.19.91.20091014-0ubuntu1 On Mon, Oct 26, 2009 at 9:08 PM, Wei Dai wei...@weidai.com wrote: Link to the bug report?

How can we find out who submitted the the binutil patch and contact him or her? I've posted to https://bugs.launchpad.net/ubuntu/+source/binutils/+bug/461303 asking that question. I suppose the patch came from upstream binutils, i.e. the Ubuntu folks acquired the patch from the binutils folks, but I'm not sure how to trace its exact provenance. I can also look at this in the debugger and see if I can fix it in Crypto++ code. Can you either give me a shell account on a machine that can reproduce this, or tell me how to reproduce this, starting with a blank VMware instance? To reproduce: Install Ubuntu Karmic Koala (release candidate or final release) Get the Crypto++ 5.6.0 source code run make run cryptest.exe v Until this is fixed, you can try to work around it by disabling the SHA256 (or all) assembly code. Thanks for the work-around idea. Maybe I could have my build script test the version of the GNU assembler and disable ASM if it is the known-bad version. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Crypto++ Users Google Group.

Oh, I should mention that this issue is known to affect the amd64 platform and it is not known if it affects other platforms. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Crypto++ Users Google Group.
