Summary0023909: FPE in BSplSLib::RationalDerivative
DescriptionRunning OCCT tests in Debug mode on Windows reveals the problem with FPE exception in BSplSLib::RationalDerivative, due to using uninitialized floating point value.
Steps To ReproduceIn Debug mode:
Draw[]> test bugs modalg_4 bug8842_5 1
...
An exception was caught 00631B80 : Standard_Overflow: FLT OVERFLOW
** Exception ** 00631B80 : Standard_Overflow: FLT OVERFLOW
Tcl Exception: ** Exception ** 00631B80 : Standard_Overflow: FLT OVERFLOW
Additional information
and documentation updates		The problem is probably due to taking value of array HomogeneousArray (pointer to HDerivatives) out of his bounds on line 178.

Committer: bugmaster Details Diff		 0023909: FPE in BSplSLib::RationalDerivative

Avoid use of array out of its bounds in BSplSLib::RationalDerivative().

In addition, Resource_Manager is fixed to allow saving with empty resource map (test bugs fclasses bug181_1).		 Affected Issues
