Can someone explain me the following behaviour ?
Is it a bug ?

cesena-29->gcc -v
Reading specs from /usr/local/lib/gcc-lib/sparc-sun/2.3.3/specs
gcc version 2.3.3
(sun4 with OS 4.1)


The following lines:

  vertebra* top = &(s[len]);
  vertebra* t = s;
  vertebra* u = v.s;
  while (t < top) *t++ = *u++; // this is line 98

cause the following error message:

../prinst/vertebra.Vec.cc:98: invalid lvalue in unary `&'
../prinst/vertebra.Vec.cc:98: invalid lvalue in unary `&'
../prinst/vertebra.Vec.cc:98: please fix above errors, and try recompiling.


The following change fixes the problem:

  vertebra* top = &(s[len]);
  vertebra* t = s;
  vertebra* u = v.s;
  while (t < top) {*t++ = *u; u++;}

????
