Bug ID: 108180
Summary: [OpenMP] Passing a class member variable to
firstprivate() erroneously calls its dtor
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org

Minimal example cpp
Following situation:
I have a class. This class has a member variable (itself of a complex type).
The class also has a member function in which an OpenMP loop (#pragma omp
parallel for) is used. This loop accesses the mentioned class member variable
through the firstprivate() flag.
As far as I understood, this should copy the variable into every worker thread
by calling the copy constructor.
However, now upon leaving the class's member function, the dtor of the class
member variable is called.
Here is a code example: https://godbolt.org/z/oxb3Pq9he
The log shows, that the dtor of the mentioned class member variable is
erroneously called twice.
