Parsing a variadic macro makes clang2py crash about ctypeslib

[FloSim82]

To help here are the 3 header files:

$ cat lib1.h

#ifndef LIB1_H
#define LIB1_H

#ifdef __cplusplus

extern "C"
{
#endif

int     lib1_init();

void    log_print(const char * module, int options, int severity, const char * color, int output, const char * fmt, ...);
#define log_print_def(fmt, ...)     log_print(NULL, 0, DEBUG_INFO, NULL, LOG_DEF_PRINT, fmt, ##__VA_ARGS__)


#ifdef __cplusplus
}
#endif

#endif

$ cat lib2.h

#ifndef LIB2_H
#define LIB2_H

#include "lib3.h"

#ifdef __cplusplus

extern "C"
{
#endif

int lib2_init();

#ifdef __cplusplus
}
#endif

#endif

$ cat lib3.h

#ifndef LIB3_H
#define LIB3_H

#include "lib1.h"

#ifdef __cplusplus

extern "C"
{
#endif

int lib3_init(void);

#ifdef __cplusplus
}
#endif

#endif
