mame is affected by what looks to be the same issue. I get the following message:

annobin: model1.cpp: CET values have changed from 32764:0:20:1000000000000 to 16:0:20:1000000000001

linking failure occurs later:

`_ZSt20__replacement_assertPKciS0_S0__end' referenced in section `.gnu.build.attributes' of ../../../../linux_gcc/bin/x64/Release/mame_mame/libsega.a(model1.o): defined in discarded section `.text._ZSt20__replacement_assertPKciS0_S0_[_ZSt20__replacement_assertPKciS0_S0_]' of ../../../../linux_gcc/bin/x64/Release/mame_mame/libsega.a(model1.o)

Same as mentioned by Scott, rawhide build works as expected. Full log is here:

https://koji.fedoraproject.org/koji/taskinfo?taskID=25582153

As you can see, the issue only affects x86_64.

This is afflicting Mir pre-release builds too: https://copr-be.cloud.fedoraproject.org/results/ngompa/mir-prerel-fedora/fedora-28-x86_64/00728338-mir/build.log.gz

Hi Guys,

  Hmm, well I am not sure why rawhide should be working, when F28 is not,
  but the solution seems obvious - sync F28 annobin with rawhide.  So this
  is what I have done.  Please could you try:  annobin-5.0-1.fc28  and let
  me know if the problem still persists.

Cheers
  Nick

Oops - I should have also mentioned that the message about "CET values have changed" is just a debugging output that I accidentally left in the plugin.
It should have no effect on plugin's behaviour and it should not be causing
the problem.

I was able to build wxGTK3 successfully with annobin-5.0-1.fc28, so that seems to have resolved the problem.  As as aside, there seems to be some different debug output now:

BUILDSTDERR: url.cpp: ICE: unknown dwarf version level -1
BUILDSTDERR: annobin: url.cpp: ICE: unknown dwarf version level -1
BUILDSTDERR: annobin: zlibstream.cpp: ICE: unknown dwarf version level -1

Hi Scott,

  Thanks for letting me know about this error message.  I am not sure
  how gcc can have a value of -1 for the DWARF version, but I have now
  added code to the annobin plugin to handle it.  Please try: 
  annobin-5.1-1.fc29 or annobin-5.1-1.fc28 and see it this makes things
  better.

Cheers
  Nick

Nick, could you please create an update for this?

annobin-5.1-1.fc28 has been submitted as an update to Fedora 28. https://bodhi.fedoraproject.org/updates/FEDORA-2018-2c415304da

It wasn't working in a scratch build earlier today: https://koji.fedoraproject.org/koji/taskinfo?taskID=25834766

I assume it's because the annobin is horrifically out of date there...

annobin-5.1-1.fc28 has been pushed to the Fedora 28 testing repository. If problems still persist, please make note of it in this bug report.
See https://fedoraproject.org/wiki/QA:Updates_Testing for
instructions on how to install test updates.
You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-2018-2c415304da

Yes, annobin-5.1-1.fc28 gets rid of the unknown dwarf version level error when building wxGTK3.

to get it into the buildroot permanently during the current beta freeze, you have to submit it as an update and nominate for freeze exception: https://qa.fedoraproject.org/blockerbugs/propose_bug (https://fedoraproject.org/wiki/QA:SOP_freeze_exception_bug_process).

Proposed as a Freeze Exception for 28-beta by Fedora user sergiomb using the blocker tracking app because:

 annobin, fix failure buildings

Discussed during blocker review [1]:

AcceptedFreezeException (Beta) - this is accepted as a freeze exception on the basis it's needed to build some packages, and pulling it in as an FE rather than using a buildroot override keeps the contents of the composes more consistent

[1] https://meetbot-raw.fedoraproject.org/fedora-meeting-1/2018-03-22/

annobin-5.1-1.fc28 has been pushed to the Fedora 28 stable repository. If problems still persist, please make note of it in this bug report.
