dpct giving SIGSEGV while converting cuda code

Hi,
I am trying to convert CUDA-Winograd usinf dpct but I am getting SIGSEGV error for all the files.Sample error for Kernel256_winograd.cu is:
c:\Users\intel\Downloads\cuda code\CUDA-Winograd-master>dpct --cuda-include-path="C:\nvcc\include" --out-root=dpct Kernel256_winograd.cu

Meet signal:SIGSEGV
Intel(R) DPC++ Compatibility Tool tries to give analysis reports and terminates...
I am getting same SIGSEGV error for /Kernel128_one.cu, Kernel128_winograd.cu and Kernel256_one.cu files too (though warnings are different)
compile_commands.json is also attached but I am getting same error with or without compile_commands.json.

Hi Gagandeep,
The issue can no longer be reproduced with Beta08. Could you please verify at your end?
