As reported in this newsgroup,
* f77 1.3 is INCOMPATIBLE with f77 1.2 (and earlier) object code.
* Version 1.3 core dumps when writing binary files, as shown below:
ccccccccccccccccccccc
program bomb
c
c change (NP=300) -> OK
c (NP,3000) -> BOMB !!!!
c
PARAMETER(NP=3000)
integer i,np,lu
real array(NP)
data lu/3/
c
open(unit=lu, form="unformatted", file="delete-me")
c
do 10 i=1,np
array(i) = 0.0
10 continue
c
write(lu) (array(i), i=1,np)
c
stop
end
cccccccccccccccccccc
So I have two questions,
1) Can an earlier version of f77 (say 1.1 or 1.2) be used
reliably with SunOS 4.1?
2) For those of you who depend on using FORTRAN on a Sun, have you
upgraded to 4.1, and if so, what other problems/difficulties have you
encountered?
