NaNs in Kobayashi1993/dendrites #79

Closed timhutton closed 4 years ago

Only affects the head of gh-pages, seen on Windows. Doesn't affect the 0.10.1 release.

After a single iteration the entire field becomes NaN:

Was introduced in ca34b027. Huh.

Removing the '-cl-fast-relaxed-math' option fixes the problem. What I still don't understand however, is why this didn't affect the 0.10.1 build which was made much later than ca34b027. Did something else change (Window/OpenCL/VisualStudio) that exposed the issue?
