Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org

Target Milestone: ---
cp/decl.c:

That would make the cleanup function have a scope attached or related to the variable being dtord. Howevr, we cannot use actual lambdas, as that'd disturb the ABI-specified mangling of function-scope lambdas. We'd need some kind of separate numbering or naming (perhaps from the variable in question?) ^ permalink raw reply [flat|nested] 3+ messages in thread
