Could you demonstrate this? My simple experiments seem to indicate that
this is not a typedef bug:
Removing the macro and typedef from your test case I still don't see
"struct S" emitted in Clang's DWARF:
+typedef struct S { int i; } *T;
+#define M(p) ((T) (p))
+
+void
+foo (void* p)
+{
+ M (p)->i++;
+}
$ clang++-tot typedef.cpp -g -c && llvm-dwarfdump typedef.o | grep DW_TAG
0x0000000b: DW_TAG_compile_unit [1] *
0x00000026: DW_TAG_subprogram [2] *
0x00000044: DW_TAG_formal_parameter [3]
0x00000053: DW_TAG_pointer_type [4]
