gcov error: Multiple sources for a single basic block

When I invoke gcov as follows it returns the following error message:

gcov -a -p dynamic-maps.gcda

Multiple sources for a single basic block: <path-to-file>/dynamic-maps.cpp !=  (in _ZN16AnalysisPipeline16AnalysisServices22calculate_dynamic_mapsERKNSt3__110shared_ptrINS_6Common16AnalysisRegistryEEERKN9Utilities6ImagesERKNS3_10TimeSeriesERKNS3_14T1ParameterFitE).
Invalid .gcno File!

Please can someone explain what the cause of this might be.

gcov -version returns:

The file was compiled using Xcode 5.1 on OS X Mavericks with the following version of clang:
