When I look at build/runtimes/runtimes-nvptx64-nvidia-cuda-bins/libc/test/integration/src/__support/GPU/libc.test.integration.src.__support.GPU.fixedbuffer_test.__hermetic__.__build__.params:

```
--threads
32
--blocks
16
---
---
LIBOMPTARGET_STACK_SIZE=3072
```

It seems to be the only one specifying threads, so that suggests that we have another bug to solve.  I'll have a PR incoming shortly for this.
