Description :

Following line causes this error:

return (*(unsigned char *)s1 - *(unsigned char *)--s2);

in following function (specs removed for clarity - and because they don't affect the issue):

int strcmp(const char *s1, const char *s2)
    {
   while (*s1 == *s2++)
      if (*s1++ == 0)
	return (0);
   return (*(unsigned char *)s1 - *(unsigned char *)--s2);
}

Replacing this line with this works but I cannot touch the code: return ((unsigned char)s1 - (unsigned char)(--s2));

Additional Information :

I'm using the bundle: Frama-C Beryllium 2 Source distribution including Why-2.21 and Jessie.

This is a blocker to use the tool as changing the code is not an option.

command line: frama-c -jessie -pp-annot -cpp-extra-args " -include e:/fama-c/share/frama-c/jessie/jessie_prolog.h" strcmp.c
