I am getting exit code -1 from the Symfony process command on some machines, while exactly the same code returns exit code 0 as excepted on others. In both cases the given command is executed successfully regarding its output.
Running the same command line from shell gives the correct exit code (0). I produced a small test case to reproduce the issue:
use Symfony\Component\Process\Process;
$process = new Process('./console');
$process->run();
echo $process->getExitCode();
Any ideas on how to diagnose this?
