Interesting ... thanks for digging deeper. I don't think I will get a chance to take a look till tomorrow though.
Piotr btw - I just accepted that last attachment email so we should see that soon. ________________________________ From: Peshala Pahalawatta [pp...@ddd.com] Sent: 25 April 2013 08:21 To: Piotr Stanczyk; openexr-devel@nongnu.org Subject: RE: [Openexr-devel] [Half] HalfTest Failure It seems like the problem does not occur in the latest stable version (1.0.3). In 2.0.0, half.h includes a file called halfexports.h which is looking for a PLATFORM* definition, so I guess that comes from an older branch?

I get an error message when running HalfTest saying, HalfTest.exe has stopped working, after the following lines: 1>Running HalfTest unit tests... 1>testing type half: 1>size and alignment 1>sizeof (half) = 2 1>alignof (half) = 2 1>ok 1>basic arithmetic operations: 1>f1 = 1, f2 = 2, h1 = -27.1875, h2 = -19.1875 The problem seems to be in assert (h1 == 3) on Line 30 of testArithmetic.cpp where it does _toFloat[_h] with _h = 52940, and _toFloat[52940] is not actually available. I’m not completely sure how _toFloat is populated. The compiler has created a toFloat.h and eLut.h file in the Half directory, so the tables seem to be already available. Any advice on this would be much appreciated. Best regards, Pesh
