Hi,

Thanks for reporting this bug. The crash is reproducible. We are working on this internally and will get back to you.

Regards,

Rahul

[Viet_H_Intel]

This is a known issue and will be fixed in the next release.

Thanks,

[Viet_H_Intel]

We have released oneAPI 2021.2, which fixed this issue.

$ cat t1.cpp

int(&&intu_rvref)[]{1,2,3,4};

$ icpx t1.cpp -c -V

Intel(R) oneAPI DPC++/C++ Compiler for applications running on Intel(R) 64, Version 2021.2.0 Build 20210317

Thanks,

[Viet_H_Intel]

Since this issue is now fixed in oneAPI 2021.2, I am going to close this thread.

Thanks,
