RUBY_CRASH_REPORT does not work in some cases when shelling out on Linux. For example, given the following shell script dump.sh:

#!/usr/bin/env bash
cat > /tmp/crash

And we see it fails like this:

$ RUBY_CRASH_REPORT="|dump.sh" ruby -rfiddle -e "Fiddle::Pointer.new(1, 10)[0]"
cat: -: Resource temporarily unavailable
