-description = """Working with numpy in a ppc64le VM, I ran into a strange double -to casting issue, specifically when casting an array of 1.0 values to 1 values. The numpy folks guided me to a small reproducible test case.
-
-The attached [convert.c](/uploads/2dd7936f4defccf816ffee7c7c002e77/convert.c) creates double and int arrays of length `1 <= n <= 16`. The double array is filled with the value 1.0, and both arrays are passed to a function that converts the value.
-
-With `-O2`, output is as expected (truncated here): 
-
-```
-i =  1:   1
-i =  2:   1 1
-i =  3:   1 1 1
-i =  4:   1 1 1 1
-i =  5:   1 1 1 1 1
-i =  6:   1 1 1 1 1 1
-```
-
-With `-O3`, all values that fit into blocks of four become zero:
-```
-i =  1:   1
-i =  2:   1 1
-i =  3:   1 1 1
-i =  4:   0 0 0 0
-i =  5:   0 0 0 0 1
-i =  6:   0 0 0 0 1 1
-```
-
-I tested this with executables compiled on a physical ppc64le host, where the issue is not reproducible."""
