ICE -init=snan EQUIVALENCE on ifort 18.0.0 (Parallel Studio XE)

Hi,

We have bumped into an issue after updating to Parallel Studio XE 18.0.0. See the details below (including the reduced test case). The following works on 17.4.0 (SLES 12 SP2). Seems like a bug in the compiler...

$ ifort -v
ifort version 18.0.0

$ cat /tmp/decext_testcase.f
      SUBROUTINE DECEXT
      EQUIVALENCE (X,Y)
      END

$ ifort -init=snan /tmp/decext_testcase.f
/tmp/decext_testcase.f: catastrophic error: **Internal compiler error: segmentation violation signal raised** Please report this error along with the circumstances in which it occurred in a Software Problem Report.  Note: File and line given may not be explicit cause of this error.
compilation aborted for /tmp/decext_testcase.f (code 1)

Best regards

I am experiencing the same problem. It seems like the compiler bug is triggered anytime varaibles are preallocated with compiler flags because the sample code I have attached also dies on a compiler error with /Qinit:arrays flag on but one of the elements in the equivalence statement is an array.

On another note, I tested the code in #1 with the internal compiler and there is no ICE in upcoming 18.0 Update 1. Please wait for the Update 1 to come out (very soon) and report any issues via Online Service Center.
