2 years ago what target system do you see this kind of flakiness, I ran the following code in a loop on my linux workstation and it always seems to return an exit code of 0.
import 'dart:io';
main() {
final ProcessResult result =
Process.runSync('uname', <String>['-m']);
if (result.exitCode != 0) {
print(
'Encountered an error trying to run "uname -m":\n'
' exit code: ${result.exitCode}\n'
' stdout: ${result.stdout.trimRight()}\n'
' stderr: ${result.stderr.trimRight()}\n'
);
} else {
print(' exit code: ${result.exitCode}\n'
' stdout: ${result.stdout.trimRight()}');
}
}

We (Flutter) run
uname -mas part of our CI automation.Every now and then, this exits with a non-zero exit code (though the program still runs and gives correct useful output). However, at least in the one time we've so far seen the exit code, it was outside the expected range of -255..255, it was 1080567520.

Source (where we call
uname): https://github.com/flutter/flutter/blob/master/packages/flutter_tools/lib/src/base/os.dart#L271I followed this code all the way to Dart's runtime/bin/process_linux.cc but then got lost. I didn't see anything between the
os.dartcode above andruntime/bin/process_linux.ccthat could explain the value being outside the expected range.
