[BUG] thread blocked indefinitely in an MVar operation

[wujilingfeng]

Description I install accelerate on WLS2, and run some code very well with accelerate-llvm-native backend. But if I use accelerate-llvm-ptx backend, it throws an error.thread blocked indefinitely in an MVar operation. I don't use stm package and any MVar operation.

Steps to reproduce if can download this code https://gitee.com/wujilingfeng/haskell-sift.

Your environment

If the bug is with the accelerate-llvm-ptx GPU backend, include the output of nvidia-device-query

• Accelerate: 1.3.0.0
• Accelerate backend(s): accelerate-llvm-ptx
• GHC: 8.10.7
• OS: windows 10 wsl2
• nvidia GTX 1660 Ti cuda-11.4

According to my recent experience, the array is probably out of bounds.

The array is not out of bounds, which seems to be a bug.
