Description Jitka Plesnikova 2020-01-23 15:04:10 UTC 
gmsh-4.5.1-1.fc32 fails to build in F32: 

/usr/bin/ld: CMakeFiles/shared.dir/contrib/mmg3d/build/sources/inout.c.o:/builddir/build/BUILD/gmsh-4.5.1-source/contrib/mmg3d/build/sources/mesh.h:411: multiple definition of `MMG_movevertex'; CMakeFiles/shared.dir/contrib/mmg3d/build/sources/mmg3d.c.o:/builddir/build/BUILD/gmsh-4.5.1-source/contrib/mmg3d/build/sources/mesh.h:411: first defined here

A difference between passing and failing build root is at 
https://koschei.fedoraproject.org/build/7747403
This is probably triggered with an upgrade of gcc from 9.2.1-1.fc32.3 to 10.0.1-0.3.fc32.

Latest 4.5.1 build succeeded and I just built 4.5.2 which also succeeded. Closing.
