It seems that the io library is leaking memory when reading logicals, as
demonstrated by the small program below; when running, the program uses more
and more memory until it's killed. I don't see this behaviour with data types
other than logicals.
erik:/var/tmp$ cat memoryleak.f90
program memoryleak
implicit none
logical :: foo
integer :: ios
ios = 0
do while (ios == 0)
read (*, *, iostat=ios) foo
end do
end program memoryleak
erik:/var/tmp$ gfortran memoryleak.f90
erik:/var/tmp$ awk 'BEGIN{while (1) print "F"}' | a.out
Killed
