Bug ID: 86633
Summary: invalid with rvalue references
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: zhonghao at pku dot org.cn
Target Milestone: ---
The code is as follow:
int x = reinterpret_cast<const int&&>(1.0f);
Consensus on IRC is that this is invalid.
g++ accepts it, but clang++ rejects it:
code0.cpp:1:9: error: reinterpret_cast from rvalue to reference type
'const int &&'
int x = reinterpret_cast<const int&&>(1.0f);
