Let's rule out bash vs. dash complexities, and first focus on whether
cygwin1.dll might be at fault.  Untested code:

#include <unistd.h>
#include <stdio.h>
#include <string.h>
#include <errno.h>
int main(int argc, char**argv)
{
  int e = chdir(argv[1]);
  char *cwd = getcwd(NULL,0);
  return printf ("chdir to %s: %d(%s), now in %s\n", argv[1],
    e, strerror(e), cwd);
}

That alone will give insights into whether you should even be expecting
this to work.  The difference between bash and dash is that bash spends
more time calling cygwin conversion routines in advance of attempting chdir.
