I want to change the exit status of the exit_error() function in
test-common.sh from 1 to 255, as that is the value that will prevent
xargs from processing further input. Currently running "... | xargs
./tools/fuzz-test.sh" will not stop on an error since xargs will catch
it and just keep going.

I just wanted to check that this wouldn't cause problems (eg on the
fuzz-bot) before making the change.

Cheers,
Evan
