I've updated a project to Xcode 3.2 and the iOS 4 SDK, and now, I don't get any local variables or arguments in gdb. I've confirmed that Debug Information Format is (still) set to "DWARF with dSYM File," the compiler is GCC 4.2 (no LLVM or Clang), and GCC_OPTIMIZATION_LEVEL is 0. Any thoughts about what I might be doing wrong?
