I don't have an answer to that, but I have seen - and worked with - several codebases which work fine when compiled with -g, but will crash (in good cases) or b

  This was on Windows with VC++, but same deal. The code that some cow-orkers had written was copying strings like "LAX" and "ORD" into `char airport[3]` using strcpy(). In debug builds, VC was allocating a whole 32-bit word, but in release builds it was packing everything on the stack. Write to it, and the terminating null ends up overwriting a byte of the next variable on the stack. Urgh. Of course, these were several hundred line functions, so the strcpy and the subsequent use of the trashed variable were a long ways away.
