            Bug ID: 29912
           Summary: smesh fails self compare on x86_64
           Product: libabigail
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: default
          Assignee: dodji at redhat dot com
          Reporter: woodard at redhat dot com
                CC: libabigail at sourceware dot org
  Target Milestone: ---

fedabipkgdiff --self-compare -a --from fc37 smesh

fails self compare. This problem probably existed in 2.1 but wasn't isolated.
However it continues to present in 2.2 trunk as of 1f51b9e8

Comparing the ABI of binaries between smesh-9.8.0.2-2.fc37.x86_64.rpm and
smesh-9.8.0.2-2.fc37.x86_64.rpm:

======== comparing'libnglib4smesh.so' to itself wrongly yielded result:

  1 function with some indirect sub-type change:

    [C] 'method virtual const netgen::GeomPoint<3>&
netgen::LineSeg<3>::StartPI() const' at spline.hpp:213:1 has some indirect
sub-type changes:
      Please note that the symbol of this function is
_ZNK6netgen10SplineSeg3ILi2EE7StartPIEv
     and it aliases symbol: _ZNK6netgen10SplineSeg3ILi3EE7StartPIEv
      'method virtual const netgen::GeomPoint<3>& netgen::LineSeg<3>::StartPI()
const {_ZNK6netgen10SplineSeg3ILi2EE7StartPIEv,
_ZNK6netgen10SplineSeg3ILi3EE7StartPIEv}' now becomes 'method virtual const

_ZNK6netgen10SplineSeg3ILi3EE7StartPIEv}'
      return type changed:
        in referenced type 'const netgen::GeomPoint<3>':
          'const netgen::GeomPoint<3>' changed to 'const netgen::GeomPoint<2>'
      implicit parameter 0 of type 'const netgen::LineSeg<3>*' changed:
        in pointed to type 'const netgen::LineSeg<3>':
          'const netgen::LineSeg<3>' changed to 'const netgen::SplineSeg3<2>'

The types that it is confusing are particularly weird.
It only seems to happen on x86_64 all the other architectures seem to compare
properly.

I think that qgis has the seme problem even with the latest trunk through
5d97da97

I could indeed see this, thanks.

I think I have a fix for this issue which I have committed at
https://sourceware.org/git/?p=libabigail.git;a=commit;h=b987db9bcbdc1bcccd52b6b44399d4e9de038975.
