Description:
------------
When encountering a "Declaration of x must be compatible with y" error with a function used by a trait, the file number references the class while the line number references the trait.

Additionally tested this on PHP 7.4 and the error persists.

Test script:
---------------
https://gist.github.com/iggyvolz/c1d34e3e0997d9c0b2d9d37512d872ff

Expected result:
----------------
Fatal error: Declaration of myTrait::foo(): string must be compatible with a::foo(): int in .../b.php on line 5

Or:

Fatal error: Declaration of myTrait::foo(): string must be compatible with a::foo(): int in .../myTrait.php on line 19

Or:
Fatal error: Declaration of myTrait::foo(): string must be compatible with a::foo(): int in .../b.php on line 5, from trait on .../myTrait.php on line 19

Actual result:
--------------
Fatal error: Declaration of myTrait::foo(): string must be compatible with a::foo(): int in .../b.php on line 19
