ICE with ATAN(y,x) and different argument kinds

[Harald1]

Hello,

the following simple program ICEs:

program main
  print *, atan (y=1.0,  x=1.0) ! OK
  print *, atan (y=1.d0, x=1.0)   ! ICE
end

I get:

 While different argument kinds are not conforming, an ICE is not nice either...

@Harald1, thanks for reporting this. That's not nice for users, but does point to a problem. I filed a bug report, CMPLRLLVM-57393. We'll let you know it's progress to a fix.

[Shiquan_Su]

The fix is in the upcoming oneapi release.
