GHC runtime linker: fatal error: I found a duplicate definition for symbol

whilst processing object file
C:\GitLabRunner\builds\78d7d3f9\0\ghc\ghc\testsuite\tests\ghci\linking\dyn\T11072gcc.run\bin_impl_gcc\libASx.dll.a
The symbol was previously defined in
C:\GitLabRunner\builds\78d7d3f9\0\ghc\ghc\libraries\ghc-prim\dist-install\build\HSghc-prim-0.5.3.o
This could be caused by:
* Loading two different object files which export the same symbol
* Specifying the same object file twice on the GHCi command line
* An incorrect `package.conf' entry, causing some object to be
loaded twice.
