Problem with GUD and gdb-use-separate-io-buffer

[David Chappaz]

Hi everyone,

I have a simple problem when using the GUD interface with
gdb-use-separate-io-buffer enabled.

As a simple way to reproduce the problem, just start from the example below:


http://www.emacswiki.org/emacs/DebuggingWithEmacs#toc2

except I slightly adjust the code to take some input from the user:

#include <stdio.h> 
 int main(int argc, char* argv[]){
   int i, n;

  printf("Enter a loop length:");
  scanf("%d", &n);
 
  printf("hello world\n");
  for ( i=0;i<n;++i){
    printf("%d \n",i);
  } 
  return 0;
 }

When gdb-use-separate-io-buffer is nil and the GUD buffer is used as I/O
buffer for the program being bebugged, it works fine.

However, with gdb-use-separate-io-buffer enabled, everything completely
hangs as soon as I hit "enter" in the I/O buffer. Any ideas what might be
going wrong ? Any ideas where to look ??

Many thanks for your help !
Cheers,
David.
