What prompted me to ask was a compiler error flag that pointed to
column 72 of the first line of the source code main program, which was
unchanged from what had previously been compiled many times. The first
thing that occurred to me was that a bad non-printing character had
somehow crept into the line, and I spent a while moving things around
and re-editing it. Without success. Eventually I found the problem,
which was that a subroutine declaration in one of my libraries had been
inadvertently removed, so that a bunch of dead code with an end
statement lurked far down in the source. I guess that was why the error
pointer was so far off.
My bigger concern is why the Fortran errors get dumped to my terminal
(cmd.exe in Windows 10) in such a way that the terminal hangs and I
have to kill the window and restart it. The first line of the error
message is OK, but subsequent lines are garbled and hang the I/O.
Whatever routines gcc uses to dump those subsequent messages, they are
not the same as what is used for the first one, or for other compiler
messages. Or their parameters are different. That's what I'd like to
track down.
Which gcc version are you using? It would be best to see if this
reproduces with a currently supported version.
Also, cmd.exe is a shell, not a terminal. The terminal is probably
conhost.exe, or maybe windows terminal if you opted to install it. There
is also mintty, but probably you'd know if you were using it.
The problem is independent of the source code being compiled.

I've been having some problems getting my source code compiled with
gfortran. In particular, I get inexplicable fatal errors with
pointers to code lines that are legal and have compiled many times
before, and the error messages are not informative and hang the
command shell I'm using (cmd.exe). There seem to be problems with
stderr, stdin, and stdout in the compiler, presumably due to
incompatible terminal assignments. I've been writing Fortran programs
continually for almost 60 years (since 1967), so it's not like I'm
new at this. Is there a forum or something where I can get advice
about this sort of thing?

You can get gfortran from w64devkit:

It is hard to comment further without more details, such as perhaps
windows version or the gcc version you are using, or the code itself.
