[Summary] Fixed issue with export built on Mavericks. There was not check on empty sets in ExportFormatSpecification class.

Browse source 
C standard, section 6.5.6.8 says:
"...if the result points one past the last element of the array object, it shall not be used as the operand of a unary * operator that is evaluated..."
So GCC compiler and CLANG compiler (Mavericks) process this operation different way. GCC returns 0 on an attempt to dereference end iterator when CLANG returns a non 0 value.
