Bug ID: 70854
Summary: ICE in gfc_process_block_locals, at
fortran/trans-decl.c:6447
Product: gcc
Version: 6.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: gerhard.steinmetz.fort...@t-online.de
Target Milestone: ---
The following code with an inner block aborts when combined with
an appropriate option -finit-*. Here "integer" and -finit-integer :
$ cat z1.f90
program p
integer :: x(2), y(2)
block
integer, parameter :: a(2) = 0
x = a
block
y = 0
end block
end block
end
$ gfortran-6 -finit-integer=-7 -c z1.f90
internal compiler error: in gfc_process_block_locals, at
fortran/trans-decl.c:6447
$ gfortran-6 -finit-local-zero -c z1.f90
internal compiler error: in gfc_process_block_locals, at
fortran/trans-decl.c:6447
---
Compiles fine without that inner block :
$ cat z2.f90
program p
integer :: x(2), y(2)
block
integer, parameter :: a(2) = 0
x = a
y = 0
end block
end
$ gfortran-6 -finit-integer=-7 -c z2.f90
$ gfortran-6 -finit-local-zero -c z2.f90
# no ICE
