>I believe this is a bug in the fortran front end.
I'm inclined to agree. I'll talk to ezmlm about getting the original
test case, to put it on my list of things to look at. Even if the
problem doesn't evidently reproduce on my Pentium II, the front end
*does* probably make the same mistake on it, and the back end might
just be "coping". I can sometimes find the bug anyway.
However, if someone wants to help me, send me the testcase, and maybe
try debugging `f771', feeding it the source file (see `g77 -v ...' to
see what command-line args it gets passed, if you are concerned
about reproducability), and get to where the bug happens.
Then do `p lineno' and `p input_filename', maybe a backtrace, and
send me the output. (egcs/gcc/README.g77 describes this a bit
more at the bottom.)
