For the test case:
program F03_2_9_3_5_2b
use omp_lib
implicit none
integer, parameter :: NT = 4
integer, parameter :: int64_t = selected_int_kind(18)
integer (kind=int64_t), parameter::DYNAMIC_MEMORY = 64000_int64_t
integer (kind=int64_t), parameter::ARRAY_SIZE = DYNAMIC_MEMORY/NT/8
integer, parameter :: EXPECTED_RESULT = 1
logical :: fail = .false.
integer :: i
integer (kind=int64_t), allocatable :: A(:)
call omp_set_num_threads(NT)
call omp_set_dynamic(.false.)
!$omp parallel
if (omp_get_thread_num() == NT-1) then
allocate(A(ARRAY_SIZE))
end if
!$omp barrier ! ensure A is allocated before the sections region
!$omp sections lastprivate(A)
! This thread sleeps to attempt to let the thread
! that executes the next section get ahead.
call sleep(5)
A = EXPECTED_RESULT+1
!$omp section
A = EXPECTED_RESULT
!$omp end sections ! implicit barrier at end of sections construct
!$omp master
! verify that all elements of the array are EXPECTED_RESULT
if (MAXVAL(A) /= EXPECTED_RESULT .or. &
MINVAL(A) /= EXPECTED_RESULT) then
print *, 'FAIL - MAXVAL(A) == ', MAXVAL(A), &
' (expected ', EXPECTED_RESULT, '), &
MINVAL(A) == ', MINVAL(A), &
' (expected ', EXPECTED_RESULT, ')'
end if
!$omp end master
!$omp end parallel
end program F03_2_9_3_5_2b
> gfortran -fopenmp test.f90
test.f90: In function 'f03_2_9_3_5_2b':
test.f90:23: internal compiler error: in single_pred_edge, at basic-block.h:658
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
Expected message (Cray compiler):
> ftn -c test.f90
/opt/cray/xt-asyncpe/3.8.20/bin/ftn: INFO: linux target is being used
MINVAL(A) == ', MINVAL(A), &
^
ftn-505 crayftn: ERROR F03_2_9_3_5_2B, File = test.f90, Line = 37, Column = 27
Continuation of character context in free source form requires an "&" as the
first nonblank character of the next line.
I tried a much simpler test:
> cat simple.f90
program test
print *, "Beginning of string &
improperly continued"
end program test
For which the Cray compiler made a similar objection:
improperly continued"
^
ftn-505 crayftn: ERROR TEST, File = simple.f90, Line = 3, Column = 12
Continuation of character context in free source form requires an "&" as the
first nonblank character of the next line.
However, the gfortran compiler did not object (it should have) and the code
actually worked in a reasonable way:
> gfortran simple.f90
> ./a.out
Beginning of string improperly continued
>
At this point, I gave up on trying to reduce the original test case that caused
the ICE.

Try using -std=f90 with and without -pedantic. gfortran allows the missing
ampersand as an extension.

OK, no need to worry about the simple.f90 case. The original test.f90 problem
is the only issue.

I tried this test case gfortran 4.6.0 (current trunk) and i do not get an ICE.
It just works. ???

Same here:
gcc version 4.4.0 20090206 -- ICE
gcc version 4.5.0 20100409 -- works
gcc version 4.6.0 20100415 -- works
With -std=f95 -pedantic, I get the diagnostic for the continuation line.
