Description
This seems to occur onlyin Release mode, and the 64 bit platform. Occassionally, the EPSG Dataset object returns NAN for reals when a legitimate value should be returned. This has shown up using Test M of the ConsoleTestCpp program.

This issue was caused by the fact that records in the Unit of Measure table with the following codes did not have factor values: 9107, 9108, 9110, 9111, 9115-9121. Whenever a projection parameter with one of the codes as the UOM code was encountered, in the missing factors would produce zeros and when factor B and divided by a zero Factor C, you get a Nan. Why this only happened in 64 bit mode, I'll never know.
