dpct giving SIGSEGV during conversion

[Shukla__Gagandeep]

Hi,

I was converting dump_reg_shmem.cu from repo cutlass and dpct gave SIGSEGV

Output:

Hi Gagan,

We are also getting the same error while migrating the file(dump_reg_shmem.cu) mentioned by you. So we are escalating it to the concerned team.

Warm Regards,

Abhishek

I don't see a segfault with the latest DPCT. See the following behavior:

C:\Users\amadhuso\Downloads\cutlass\examples\02_dump_reg_shmem>dpct --extra-arg="-I../../tools/util/include" --extra-arg="-I../common" --extra-arg="-I../../include" --out-root=dpct dump_reg_shmem.cu
