multiple definitions build failure on armv7hl only

[Orion Poplawski]

Test building the latest gdl, I get the following errors only on armv7hl:

/usr/bin/ld: CMakeFiles/gdl.dir/basic_op.cpp.o:(.rodata+0x30): multiple 
definition of `typeinfo name for Data_<SpDByte>'; 
CMakeFiles/gdl.dir/datatypes.cpp.o:(.rodata+0x50): first defined here
/usr/bin/ld: CMakeFiles/gdl.dir/basic_op.cpp.o:(.data.rel.ro+0x0): 
multiple definition of `typeinfo for Data_<SpDByte>'; 
CMakeFiles/gdl.dir/datatypes.cpp.o:(.data.rel.ro+0xc): first defined here

Full log: 
https://kojipkgs.fedoraproject.org//work/tasks/5149/42205149/build.log

Anything immediately suspicious here?  Seems odd to have two definitions 
in different segments of the same object file.

This appears to be related to C++ template instantiation.  What I've yet 
to figure out is whether or not this is truly a problem in the code or 
an issue with the arm gcc/binutils tooling.  Any help would be greatly 
appreciated.

I think I have just met the same problem when building codeblocks -
https://koji.fedoraproject.org/koji/taskinfo?taskID=42870235

/usr/bin/ld: .libs/cbkeyConfigPanel.o:(.rodata+0x14): multiple definition of `typeinfo
name for cbKeyBinder'; .libs/cbkeybinder.o:(.rodata+0x0): first defined here
/usr/bin/ld: .libs/cbkeyConfigPanel.o:(.data.rel.ro+0xc): multiple definition of `typeinfo
for cbKeyBinder'; .libs/cbkeybinder.o:(.data.rel.ro+0x0): first defined here
