“bad codegen, pointer diff” linker error with Xcode 4

Question

Recompiling a C++ iPhone app with Xcode 4 I get this nasty linker error:

ld: bad codegen, pointer diff in __static_initialization_and_destruction_0(int, int)         


        

Answer 1

The solution is to set Symbols Hidden By Default to Yes in all the build settings of all targets in the project. Still none the wiser what the actual problem was.
