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

#include 
#include 
#include 

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);

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

#include 
#include 
#include 

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);
