Description Jan Kratochvil 2016-02-24 19:35:43 UTC 
Description of problem:
All recent Koji builds F24+ (gcc6?) print dwz error message.

Version-Release number of selected component (if applicable):
dwz-0.12-2.fc24.x86_64

How reproducible:
Always.

Steps to Reproduce:
Build anything in Koji, such as gdb:
https://kojipkgs.fedoraproject.org//packages/gdb/7.11/55.fc25/data/logs/x86_64/build.log

Actual results:
dwz: ./usr/lib64/libinproctrace.so.debug: Couldn't find DIE referenced by DW_OP_GNU_implicit_pointer
dwz: ./usr/bin/gdbserver.debug: Couldn't find DIE referenced by DW_OP_GNU_implicit_pointer
dwz: ./usr/bin/gdb.debug: Couldn't find DIE referenced by DW_OP_GNU_implicit_pointer
dwz: Too few files for multifile optimization

Expected results:
No error.

Comment 1 Jakub Jelinek 2016-02-24 20:03:33 UTC 
Broken by http://gcc.gnu.org/r231762 , will need to reduce and debug.
Comment 2 Jakub Jelinek 2016-02-24 20:32:16 UTC 
I've filed PR69947 to track this.
Comment 3 Jakub Jelinek 2016-03-05 07:48:25 UTC 
Should be fixed in gcc-6.0.0-0.13.fc24.
