The spawn family of calls in libexpect seg faults.
This issue is documented here

1) Create a project
$installDir/configure --enable-board=intel-x86-64 --enable-kernel=standard --enable-rootfs=glibc-small --with-package=expect --with-rcpl-version=0021
2) Export the sdk and build this source code, do not forget to use "-lexpect5.45"
#include <stdio.h>
#include <expect.h>
int main()
{
exp_spawnv("ls", NULL);
printf("Hello World\n");
return 0;
}
3) Run the software on the target (I used QEMU), you will get this error
root@qemu2:~# ./a.out
a.out[402]: segfault at 410 ip 00007fd9ffd06fee sp 00007ffd76c5c380 error 4 in libexpect5.45.so[7fd9ffce8000+2c000]
