Bug ID: 373192
Summary: Calling posix_spawn completely broken
Product: valgrind
Version: 3.12.0
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: jsew...@acm.org
Reporter: megahal...@gmail.com
Target Milestone: ---
Executing the program below with valgrind 3.12 built from sources on Fedora 25
gives the following output:
pid 21786 child 21787 r 0
pid 21787 child 83036382 r 0
Without valgrind:
pid 21805 child 21806 r 0
<output from ls>
Valgrind completely breaks the posix_spawn call by causing some kind of fork
and also not executing the ls.
#include <unistd.h>
#include <spawn.h>
#include <stdio.h>
int main()
{
pid_t pid;
char cmd[] = "ls";
char* arg[] = { cmd, NULL };
int r = posix_spawnp(&pid, cmd, NULL, NULL, arg, NULL);
fprintf(stderr, "pid %d child %d r %d\n", getpid(), pid, r);
}
