Recently, I've been testing gfortran builds of some molecular dynamics code;
AMBER (http://amber.scripps.edu/) and found a strange quirk in the READ
function when using namelists. I'm not sure if this is a bug; but the behaviour
is inconsistent with other F90 compilers. The host system is i686 Fedora Core 5
running gcc-gfortran 4.1.1 ( gcc version 4.1.1 20060525 (Red Hat 4.1.1-1)).
>From my testing, I've managaged to generate the following testcase:
program main
integer ihp(2,2)
NAMELIST /test/ ihp
open(UNIT=22, STATUS='scratch')
write (22, '(a)') &
"&test", &
"ihp(1,1) = 2*1", &
"ihp(1,2) = 2", &
"/"
rewind (22)
READ (UNIT=22, NML=test)
print *,ihp
end program main
With gfortran, the following error is returned on execution:
$ gfortran ./test.f90 -o ./test ; ./test
At line 16 of file ./test.f90
Fortran runtime error: Repeat count too large for namelist object ihp
But, if the code is compiled with ifort 9.0.033:
$ ifort ./test.f90 -o ./test ; ./test
1 1 2 0
The "expected" behaviour is seen.
