When I have to debug an error like this:

Fatal error: Cannot redeclare session() (previously declared in D:\web\sessions.php:2) does not tell me what file included the file with the session function. That forces me to do pointlessly convoluted debug.

I've tried doing back tracing however the error is reported and the process shuts down so I don't get the second back trace.

Test script:
An overly simplified version:
include('file1.php');//includes session.php.
include('file2.php');//includes session.php; error spawns, no second back trace.

Expected result:
A much more useful error message would look something like:

Fatal error: Cannot redeclare session() (previously declared in D:\web\sessions.php:2, file included by file1.php, file included by file2.php).

Use include_once instead, and don't get an error in the first

Anyhow, I don't think this qualifies as a bug, but is more like a
feature request.
