Well, since it relies on uninitialized variables, it's a bit hard to reproduce.
The following code (I believe it is legal) reproducibly fails for me on
i686-linux:
integer dat(5)
dat = (/ 0, 0, 0, 0, 18651460 /)
write(11) dat,dat,dat
rewind 11
write(11) dat,dat,dat,dat
rewind 11
write(11) dat
rewind 11
write(11) dat
rewind 11
read(11) dat
read(11,end=1008) dat
1008 continue
backspace 11
write(11) dat
backspace 11
read(11) dat
read(11,end=1011) dat
1011 continue
backspace 11
backspace 11
end
I think it has to do with array transfer, and overwriting the record markes
with data. Adding Janne in CC list for opinion.
