@iron_bug I don't know, it's a mess; usually this kind of thing happens after a personnel change. I'm not sure what version it was but a long time back I was debugging something, I put a `printf("About to do the thing before the bug happens\n");` and gcc silently translated it to puts(), so I set a breakpoint on printf and the program never stopped, my breakpoint didn't happen (and mangled the constant in the binary).
