Bug ID: 107037
Summary: 541.leela_r compiling fail since r13-2779
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: guojiufu at gcc dot gnu.org
Target Milestone: ---
When building 541.leela_r from spec2017, I encounter one error:
include/c++/13.0.0/bitset: In instantiation of 'void
std::_Base_bitset<_Nw>::_M_do_reset() [with long unsigned int _Nw = 7]':
include/c++/13.0.0/bitset:1145:19: required from 'std::bitset<_Nb>&
std::bitset<_Nb>::reset() [with long unsigned int _Nb = 441]'
Playout.cpp:20:18: required from here
include/c++/13.0.0/bitset:187:13: error: forming reference to reference type
'long unsigned int (&)[7]'
187 | for (_WordT& __w : _M_w)
| ^~~
The command is
g++ -std=c++03 -m64 -c -o Playout.o -DSPEC -DNDEBUG -I.
-DSPEC_AUTO_SUPPRESS_OPENMP -Ofast -DSPEC_LP64 Playout.cpp
This issue is also reproducible on -O3 or -O2.
It seems compiling fine before commit
r13-2779-9194c13909b72d23e58fee72864a2663b12f6b19.
