[Request] Show which test fail in Fatal error

[lambdalisue]

It would be nice if I can see which test is failed even when Fatal error occur with dot report like

FATAL ERROR: 
.........................................................................................................................................................................................................................................................................................................................................................................................................................................................................................PP........................................................................................................................................................................................
Error occurred in core.
Command exited with code 1

It is quite difficult to figure out which test or file cause the fatal error
