[Bug c++/18905] New: Strange error: subscripted value is neither array nor pointer

["schnetter at aei dot mpg dot de" <gcc-bugzilla at gcc dot gnu dot org>]

With gcc 4.0.0 from today (December 9, 2004), I receive the error message 
 
error: subscripted value is neither array nor pointer 
 
for a piece of code that looks fine and is accepted by Intel's icc.  Some 
relevant lines seem to be e.g. 
 
 const char* const coords = "xyz"; 
 for (int d=0; d<D-1; ++d) os << "i" << coords[d] << " "; os << "i" << 
coords[D-1]; 
 
which looks as if there was a problem indexing the "coords" string. 
 
I compile with the options 
 
$ /home/eschnett/gcc/bin/g++ -ftrapv -march=pentium4 -malign-double -g3 -c 
ioascii.ii 
 
and the screen output is
