ifort version 188.8.131.52 gives ICE for:
ifort -c intel_ICE.F90
/tmp/ifort9yOGb6.i90: 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 intel_ICE.F90 (code 1)
Where intel_ICE.f90 contains only:
a = atan(x)
b = atan(y, x)
It seems the root cause is having the Fortran 2008 atan(y,x) in the same program unit as atan(x), which should be perfectly legal.
This also happens with ifort 18. 18.3, 19. Ever since this feature was added.
For some reason I cannot login to support center. Hopefully an admin could pass this info along.
