gelu example wgpu segfault

[wbrickner]

The gelu example segfaults with the wgpu backend, but only some of the time (about 20%).

The result always prints, then the segfault occurs:

Executed gelu with runtime "wgpu" => [-0.15865529, 0.0, 0.8413447, 4.9999986]
Segmentation fault (core dumped)

The segfault occurs in the [vkps] Update thread. That's all I know.

I can't view the call stack of this thread and the other threads are in boilerplate rust symbols or some futex/pthread lock symbols.

I can't reproduce it. I think we would need a bit more info to spot the potential bug 😅
