Try to compile the following code in a cpp file, gcc crashes. Working on Redhat 7.2.

#include <assert.h>

#define b 5
int f;
int foobar(int foo, int bar = (assert(f>=b), funcPtr)(), int foob=some_int);

Reading specs from

The following code also crashes. Can somebody suggest a workaround while I am
using gcc 3.2

#include <assert.h>
#include <stdio.h>
#include <stdlib.h>

extern bool cond;

int (*funcPtr)();
#define printf 

int foobar(int foo, int bar = ((cond?funcPtr:(fprintf(stderr, "problem at
%s:%s\n", __FILE__, __LINE__), abort()))()), int foob=8);

I am planning to use the following code as workaround, which does not crash.

#include <assert.h>
#include <stdio.h>
#include <stdlib.h>

extern bool cond;

typedef int (*FuncPtr)();

FuncPtr funcPtr;

int foobar(int foo, int bar = ((cond?funcPtr:(fprintf(stderr, "problem at
%s:%s\n", __FILE__, __LINE__), (FuncPtr)0))()), int foob=8);

3.2.x is so old and not maintained any more and ther other one is fixed also already in 3.3, I think it is 
time to update.
