Bug ID: 110081
Summary: Unhelpful error message: "(null):0: confused by
earlier errors, bailing out"
Product: gcc
Version: 12.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: andrew at fluidgravity dot co.uk
Target Milestone: ---
The following code compiles with neither gfortran-11 nor gfortran-12, but does
compile with gfortran-10 and earlier. The error message just says "(null):0:
confused by earlier errors, bailing out" without giving any indication what the
problem is. (The actual problem seems to be the clash between the variable name
'p' in the common block and the module name 'p'.)
MODULE commons
IMPLICIT NONE
INTEGER :: p
COMMON /c/ p
END
MODULE p
IMPLICIT NONE
SAVE
CONTAINS
SUBROUTINE sub
USE commons
END SUBROUTINE sub
END
$ gfortran-11 -c code.f90
