The follwing program:
#include <stdio.h>
#define LOG
FILE *log_file;
int f2 (int x)
{
#ifdef LOG
static long toto = 0;
static const char *fname = __func__;
static void __attribute__ ((destructor)) f (void) {
fprintf (log_file, "%s: toto=%ld\n", fname, toto);
}
toto += x;
#endif
return 42;
}
int main ()
{
log_file = fopen ("toto.log", "w");
f2 (3);
return 0;
}
failed to compile with GCC 4.0.0 and GCC 4.0.1:
