Comment 1 Alexander Simon 2014-08-28 09:14:10 UTC 
Test case:
C file:

// This pounds on macro expansion for performance reasons.  This is currently
// heavily constrained by darwin's malloc.

// Object-like expansions
#define A0 a b
#define A1 A0 A0 A0 A0 A0 A0
#define A2 A1 A1 A1 A1 A1 A1
#define A3 A2 A2 A2 A2 A2 A2
#define A4 A3 A3 A3 A3 A3 A3
#define A5 A4 A4 A4 A4 A4 A4
#define A6 A5 A5 A5 A5 A5 A5
#define A7 A6 A6 A6 A6 A6 A6
#define A8 A7 A7 A7 A7 A7 A7
