I'm a recent reader of net.bugs.4bsd (two weeks or so now), and I have
a request for help with f77 on both 4.2BSD and Ultrix 1.[12]. First,
here's a bug report:
Symptom:
The f77 compiler will not optimize a concatenation of varying-
length character strings under Ultrix 1.[12].
Reproduce by:
Create the following file and do f77 -O -c:
subroutine bug(str1, str2)
character*(*) str1, str2
character*100 str3
str3 = str1//str2
return
end
You will get two "Error in line 4: impossible element in
concatenation" messages.
Fix:
Unknown
Does anyone out there have a fix for this problem (we don't have source at
our site)? More generally, has anyone been saving up previous patches
to f77 under either 4.2BSD or Ultrix someplace where they can be mailed
to me and/or I can FTP them? The 4.2 stuff is less important, since
we'll be installing 4.3 in two weeks or so.
Thanks very much! Please email replies to:
