$ cat osdep.i  
static void do_date (char *);  
void rfc822_date (char *date)  
{  
  do_date (date);  
}  
$ gcc -c -O2 -fno-omit-frame-pointer -w osdep.i  
osdep.s: Assembler messages:  
osdep.s:19: Error: Epilogue count of 4294967296 exceeds number of nested  
prologues (0)  
  
This is due to an extra '.restore sp' before the tail call.
