We really should consider not to take the CalculiX of 8.2 libpack and the Cygwin of FreeCAD 0.14 instead. Even gcx (the original result viewer of CalculiX) has problems with this resultfile which has spaces missing. Tested to run this CalculiX from windows shell and the spaces are still missing. So it is not a FreeCAD problem.
EDIT:
The if statement here takes exact column numbers for reading which is not possible anymore if the spaces are missing due to positiv or negativ character (https://github.com/FreeCAD/FreeCAD_sf_m ... Lib.py#L96)
