Thanks, can you show a use case where such a problem happens?

Yes, basically any program with more than one source file and a large screen (display-buffer will reuse window if there aren't enough space).

A minimal setup:


int f1(int a) {
    return a + 1;


#include "a.c"

int main() {
    int b = f1(1);
    int c = 0;
    return b + c;

- M-x gdb
- b main
- r
- s (many times)

And when you step into f1 which is in a.c, gdb opens another window to display it (again, if your screen is large enough).

BTW, I say "by design gdb uses a single source window" because gdb-display-source-window is written that way.
