[SciPy-User] testieee NaN arithmetic did not perform per ieee spec with ifort

Dear all,

compiling the lapack 3.4.1 with Intel's ifort compiler results in the 
test program "testieee" not passing the NaN test:

"NaN arithmetic did not perform per the ieee spec"

When compiled with gfortran it passes this test.
Should I worry? Will the ifort compile work so much faster that it's 
worth the little worry? (I will be working a lot with data binnings and 
griddings, interpolations, fittings…)

Best regards,
