From: Michael Welsh Duggan <mwd <at> md5i.com> To: bug-gnu-emacs <at> gnu.org Subject: 30.0.50; RET in source files that are being displayed by gud no longer works Date: Sun, 29 Jan 2023 21:07:58 -0500
Create a trivial C program. Here's a good example:
int main()
{
return 0;
}
Save it as foo.c, and compile it with debugging:
gcc -ggdb3 -o foo foo.c
From emacs -Q, start gdb on foo:
M-x gud-gdb RET
In my case, since foo is the only executable in the dir, the command
line for gdb is already set up correctly as:
gdb --fullname foo
Hit RET. You should be at the gdb prompt. Start the program:
start RET
You should now get another window with foo.c in it for context. Switch
to that buffer and type RET.
C-x o
RET
In my case, I get:
comint-send-input: Current buffer has no process
This is new and broken behavior. The expected behavior is that a
newline is inserted in the buffer.
