Bug ID: 23371
Summary: Setting up stdio redirection does not work if inferior
started in synchronous mode (-o run)
Product: lldb
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: lldb-dev@cs.uiuc.edu
Reporter: lab...@google.com
Classification: Unclassified
I think the example says it all:
$ cat a.c
#include <stdio.h>
int main()
{
int i;
printf("enter a number: ");
scanf("%d", &i);
printf("got %d\n", i);
return 0;
}
$ gcc a.c
$ lldb a.out -o run
(lldb) target create "a.out"
Current executable set to 'a.out' (x86_64).
(lldb) run
enter a number: 47
42
...
