That may also explain why you haven't been able to reproduce the issue by compiling a kernel: using four threads, no single core will see a continuous 100% load for an extended period of time, as it's periodically interrupted by disk I/O. You could try compiling using twice or three times as many threads as you have CPU cores, and see if the system remains stable.
It may still not crash, as I suspect that unlike a compiler, a video decoder will make extensive use of SIMD CPU instructions that activate a lot more circuitry.

VLC uses 4 cores, but loaded lightly. So one core isn't flat out but three or 4 are running. The four together total about 100% on my test video that locks up repeatedly.
And yes, we are down to 1800Mhz - 2000Mhz being the issue. Considering there's a 1-2% QC pass rate for modern chips, it's hardly that surprising. There's millions of transistors in there, and no way of knowing which is fault prone or what it's effect is.
