…33 System Crashes Later…
Since the shader I crashed my system with does so extremely reliably, I decided to submit it as a bug report to NVIDIA. Which is a bit problematic, because this usually requires a ‘repro case’, ie. a piece of code which can reproduce the problem as repeatably as possible. Repeatability is easy - my shader crashes the machine every time - but ideally that code should also be as short as possible. Simpler examples make it easier to diagnose the problem, which in turn leads to a quicker fix. Additionally, I don’t feel too happy about preseting my latest - and unpublished - research work on a silver tablet…
So, I sat down today and tried to boil the shader down to its bare essentials, removing as much code as possible (and simplifying what was left) while it still crashed the system. An extremely annoying task I might add, but as mentioned in the topic, 33 system crashes later I’ve arrived at something reasonably simple and have already submitted it as a bug report. We’ll see how long the guys at NVIDIA take to analyze it; with my last bug report (for FX Composer) it was merely a matter of minutes…
