Summary: ambigous call on different std::variant types with
iterators
Product: gcc
Version: 11.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: benni.probst at gmx dot de

dataContainer switching between container Types, reading with std::variant
iterator types
the compiler cannot see the difference:
