internal error cgreg 371
when compiling following code with
	dmc -o+speed dirTree.cpp
error goes off when
1) no optimization
2) no use of sprintf
3) no use of for

-------- dirTree.cpp -----------
#include <stdio.h>

static inline char *make_path ( const char *base, const char *fname ) {
  static char buf[260];
  _snprintf ( buf, sizeof(buf), "%s/%s", base, fname );
  buf[sizeof(buf)] = '\0';
  return buf;
}

bool walk_dir_tree ( const char *root_dir, int wildcard_num, const char **wildcards ) {
  for ( int i = 0; i < wildcard_num; i ++ )
    make_path ( root_dir, wildcards[i] );
  return true;
}

         ^^^^^^^^^^^
Indexing one behind last element. I don't think the compiler will show
internal error because of this, but who knows ;-)
