gfortran seems to ignore explicit return types of functions.
Example follows:
-----------------------------bug.for--------------------------------
PROGRAM BUG
external real function Mfunc
real*4 X,Y
X = Xfunc()
Y = Mfunc()
write(6,*) X,Y
stop
end
real function Xfunc()
Xfunc = 17.232
return
end
real function Mfunc()
Mfunc = 17.232
return
end
-----------------------------bug.for------------------------------
When run, this gives:
17.23200 1.0995535E+09
STOP 0
Compilation was:
[...]/gfortran -Wall -o bug bug.for -L[...]/lib64 \
-Wl,-rpath,[...]/lib64
(Long path names replaced with [...]).
As usual, thank you very much. The gcc collection is a wonderful
tool.
-Mike

> PROGRAM BUG
> external real function Mfunc
This declares an external symbol called
"realfunctionmfunc" (fixed form), which is
probably not what you intended.
If you replace that line by
real Mfunc
external Mfunc
things work. If you try to compile this in free form
(extension .f95), you get a syntax error.
I'm resolving this as "invalid". Feel free to re-open it
if you believe that I haven't addressed the issue correctly.

Thank you very much. My apologies. I don't understand Fortran as
well as I should.
Sincerely,
