| I managed to end up with a piece of code which, distilled down, looks like this
void *ptr = base_ptr; void *other_ptr = ptr + 3;
when debugging through the code I used the _expression_ evaluator in lldb to evaluate "ptr+3" and I got an error message that arithmetic on void pointers is disallowed .. and I seem to remember it IS disallowed, in C at least.
But I get no warning on that line. Is there a warning flag I'm missing here? clang compiles it without warning or error, LLDB refuses to evaluate it, one of them is right, which? |
