Bug ID: 89001
Summary: g++ uses wrong mangling for lifetime-extended
temporaries
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: richard-gccbugzilla at metafoo dot co.uk
Target Milestone: ---
Consider:
inline int &&r = 0;
int *p = &r;
GCC mangles the lifetime-extended temporary as _ZGR1r0, which doesn't match the
ABI mangling rule
(http://itanium-cxx-abi.github.io/cxx-abi/abi.html#mangling-special-temporaries).
The mangling required by the ABI (and produced by Clang) is _ZGR1r_
