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:
a.c:
int f1(int a) {
return a + 1;
}
b.c:
#include "a.c"
int main() {
int b = f1(1);
int c = 0;
return b + c;
}
Steps:
- 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.
