How to detect FILE name and LINE of last php execution point statement?

I see white screen.

Somewhere my php script finished its execution.

There are no php errors or warnings. There is a lot of framework files to go through var_dump to detect place, where the script die.

Likely, some of Framework file calls die() or exit.

How can I detect last php statement? (FILE and LINE)

The statement for PHP which finished its execution without going though endless files and endless var_dump?
