CVS misc/pwd bug on Solaris 9

[Albert Chin]

Oddly, misc/pwd from CVS fails on Solaris 9 but works on Solaris
2.5.1-8:
  $ PATH=/opt/TWWfsw/perl582/bin:$PATH VERBOSE=yes gmake check TESTS=pwd
  gmake  check-TESTS
  gmake[1]: Entering directory `/opt/build/coreutils-5.3.0/tests/misc'
  /opt/build/coreutils-5.3.0/tests/misc/../../src/pwd: memory exhausted
  pwd: /opt/build/coreutils-5.3.0/tests/misc/pwd.tmp/3587/zzzzzz...
  ...
  FAIL: pwd

The "zzzz" continues ad infinitum. I have the latest kernel and libc
patch. I used the same compiler and compiler options on both Solaris 8
and 9 yet 9 crashes and 8 does not. I modified lib/xgetcwd.c from:
  while (1)
    { 
      char *buf = xmalloc (buf_size);
      char *cwd = getcwd (buf, buf_size);
      int saved_errno;
      if (cwd)
        return cwd;
to:
  while (1)
    { 
      char *buf = xmalloc (buf_size);
      char *cwd = getcwd (buf, buf_size);
      int saved_errno;

printf("buf_size: %lu\n", buf_size);
printf("cwd: %lx\n", cwd);
      if (cwd)
        return cwd;

and saw the following on Solaris 8:
  $ cd tests/misc
  $ VERBOSE=yes gmake check TESTS=pwd
  ...
  pwd: /opt/build/coreutils-5.3.0/tests/misc/pwd.tmp/1870/zzzzz...
  buf_size: 128
  cwd: 0
  buf_size: 256
  cwd: 0
  buf_size: 512
  cwd: 0
  buf_size: 1024
  cwd: 0
  buf_size: 2048
  cwd: 0
  buf_size: 4096
  cwd: 0
  buf_size: 8192
  cwd: 0
  buf_size: 16384
  cwd: 28930

and on Solaris 9:
  $ cd tests/misc
  $ VERBOSE=yes gmake check TESTS=pwd
  pwd: /opt/build/coreutils-5.3.0/tests/misc/pwd.tmp/1870/zzzzz...
  ...
  buf_size: 128
  cwd: 0
  buf_size: 256
  cwd: 0
  buf_size: 512
  cwd: 0
  buf_size: 1024
  cwd: 0
  buf_size: 2048
  cwd: 0
  buf_size: 4096
  cwd: 0
  buf_size: 8192
  cwd: 0
  buf_size: 16384
  cwd: 0
  buf_size: 32768
  cwd: 0
  buf_size: 65536
  cwd: 0
  ..

Is this a Solaris 9 getcwd() bug?
