Testcase

I stumbled on it while trying to generate docs for Firefox, here's a minimized testcase:

---

[a.cpp]

#include "a.h"

#define N(f)

enum e {
#define M N
#include "a.h"
};

---

[a.h]

#define M

M(
A |
//'
B
)

#undef M

---

With MACRO_EXPANSION enabled (all other settings are default), this example causes Doxygen 1.8.2 to stall on preprocessing a.cpp (100% core usage, runs infinitely).

Confirmed. Should be fixed in the next release.

This bug was previously marked ASSIGNED, which means it should be fixed in
doxygen version 1.8.3. Please verify if this is indeed the case. Reopen the
bug if you think it is not fixed and please include any additional information
that you think can be relevant.
