It appears that create_gcov doesn't support binaries with dwarf version 5 (which is the current default). I tried a trivial example and got reasonable gcov files for binaries with dwarf v2, v3, and v4 but the same example with dwarf v5 produced "File './sort' has mangled .debug_info section." and a gcov file with 0 functions.
Does create_llvm_prof has the same limitation?
