944,Duplicate C symbol names,PaulVanDerWalt,,"I've run into a problem where I want to include the vty and haskeline packages, which both contain the same C code, of which the symbol names are not translated or made unique. When I use both packages, and try to compile something which has Template Haskell (which triggers loading of all dependencies), I get the following error.

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

A workaround is to patch the libraries to make the function names unique, but this is less than ideal. ",defect,new,normal,,Cabal library,1.14.0,normal,,,,unknown,7.2.2,Mac OS
