Took me ages to narrow this one down. See the comments in the code below for the 2 lines that appear critical to triggering this bug.
[fortran]
MODULE MOD_ONE
IMPLICIT NONE
TYPE :: RTP_REAL
CONTAINS
PROCEDURE :: RTP_ASSIGN_REAL
GENERIC :: ASSIGNMENT(=) => RTP_ASSIGN_REAL ! Commenting this line out avoids ICE
PROCEDURE :: INIT => RTP_INIT_REAL
END TYPE RTP_REAL
CONTAINS
SUBROUTINE RTP_INIT_REAL(SELF)
IMPLICIT NONE
CLASS(RTP_REAL), INTENT(INOUT) :: SELF
END SUBROUTINE RTP_INIT_REAL
SUBROUTINE RTP_ASSIGN_REAL(SELF,VAR)
IMPLICIT NONE
CLASS(RTP_REAL), INTENT(INOUT) :: SELF
REAL :: VAR
END SUBROUTINE RTP_ASSIGN_REAL
END MODULE MOD_ONE
MODULE MOD_TWO
USE MOD_ONE
PRIVATE ! Commenting this line out avoids ICE
END MODULE MOD_TWO
SUBROUTINE TESTSUB
USE MOD_TWO
END SUBROUTINE TESTSUB
[/fortran]
Compiled using
[bash]ifort test.f90[/bash]
Here is what I see with12.0.2 20110112:
[bash]test.f90: 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 test.f90 (code 1)[/bash]
Here's to hoping there's a quick fix.
