This problem probably existed in 2.1 but wasn't isolate= d. 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: =3D=3D=3D=3D=3D=3D=3D=3D comparing'libnglib4smesh.so' to itself wrongly yie= lded result: =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D Functions changes summary: 0 Removed, 1 Changed, 0 Added function Variables changes summary: 0 Removed, 0 Changed, 0 Added variable 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>::Start= PI() const {_ZNK6netgen10SplineSeg3ILi2EE7StartPIEv, _ZNK6netgen10SplineSeg3ILi3EE7StartPIEv}' now becomes 'method virtual const netgen::GeomPoint<2>& netgen::SplineSeg3<2>::StartPI() const {_ZNK6netgen10SplineSeg3ILi2EE7StartPIEv, _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 compa= re properly. --=20 You are receiving this mail because: You are on the CC list for the bug.=
