Confirmed as working under 3.2.4 and not working at tip (11313:988d2bd6bacd).  This was on a Linux, x86_64 machine so it is not a MS Windows build issue.

error: reshape: can't reshape 1x1 array to 1x0 array
error: called from:
error:   C:\tmp\vs2008_test\oct_test\octave-3.3.54+\share\octave\3.3.54+\m\general\repmat.m at line 65, column 7

under Matlab and 3.2.4, it works with s being reported as:

s =
  1x0 struct array containing the fields:
