1 function with some indirect sub-type change:

  [C]'method HeapLeakChecker* HeapLeakChecker::GlobalChecker()' has some
indirect sub-type changes:
    return type changed:
      in pointed to type 'class HeapLeakChecker':
        1 data member change:


When checking an ABI against itself it shouldn't fail. Some ABI information is
being lost.

Created attachment 8646

another reproducer

This one produces more errors and is much smaller.

A more extreme example is:

libvtkDomainsChemistry-6.1.so
Functions changes summary: 0 Removed, 2 Changed, 0 Added functions
Variables changes summary: 0 Removed, 0 Changed, 0 Added variable

2 functions with some indirect sub-type change:

  [C]'method void std::vector<vtkVector3f, std::allocator<vtkVector3f>
>::_M_insert_aux(__gnu_cxx::__normal_iterator<vtkVector3f*,
std::vector<vtkVector3f, std::alloc\
ator<vtkVector3f> > >, const vtkVector3f&)' has some indirect sub-type changes:
      parameter 1 of type 'class __gnu_cxx::__normal_iterator<vtkVector3f*,
std::vector<vtkVector3f, std::allocator<vtkVector3f> > >' has sub-type changes:
            1 data member change:

    parameter 2 of type 'const vtkVector3f&' changed:
          in referenced type 'const vtkVector3f':

  [C]'method std::vector<vtkVector3f, std::allocator<vtkVector3f> >*
vtkProteinRibbonFilter::Subdivide(int)' has some indirect sub-type changes:
      return type changed:
            in pointed to type 'class std::vector<vtkVector3f,

                    1 base class change:

It is hard for me to tell if these are the same problem or a different one
