I've created a different shadertoy showing the problem:
https://www.shadertoy.com/view/Wt2SW1 (but this one doesn't hang the GPU).
The shader for "Buffer A" is:
0: MOV TEMP[0], SV[0]

Here's my understanding of the issue.
This shader uses 2 passes:
- the first pass has BufferA as input and output and does:

// init bufferA content
else
// do something

I could reproduce the issue on a Raven Ridge and a Navi10.
But when using NIR (radeonsi_enable_nir=true env variable) the shader is
perfectly usable.
