1944,round function causes cblas NaNs,SevenThunders,,"After calling the round function, a call to an external C function causes NaNs to appear in the calculation.  The external C function in this case is the BLAS function cblas_dgemm() from the atlas library.  The cblas library was compiled on a 32 bit windows XP machine. The same bug occurs on my 64 bit dual core athlon under windows.  I suspect the Atlas version number was 3.7.33.  I have enclosed the source files but can not include the binary atlas library due to size constraints.  I will provide a link to an uploaded version of the binary library shortly.  I also enclosed the .bat script I used to compile the simple case.  Please note this example works just fine for ghc 6.6.1 which I also verified.",bug,closed,normal,6.10 branch,Compiler,6.8.1,fixed,,,Windows,x86,,Unknown,,,,
