Finally I was able to repro the issue with the following two lines:
session_set_save_handler(new SessionHandler());
session_start();
When I do this, I get a WSOD! Any idea why this happens?
============================================================
Finally, I digged deeper and deeper and narrowed it down to the issue being caused because of failure in session_start(); Still, I do not know why it fails that way.
So, the problem boils down to:
When session_start() is called in NativeSessionStorage::start(), it fails. However, when I create a sample test page which just does session_start() it succeeds!
Does Silex do anything different?!
I am keeping the text below so that anyone facing similar issue understands the reason behind the failure.
============================================================
I have tried to switch from Php 5.3 to Php 5.4 recently and my website based on Silex stopped working with a WSOD.
I checked the PHP Error Logs and I see:
Premature end of script headers: php54.cgi
I tried doing a lot of stuff and finally thought of asking it online :(. Here's what I tried:
Added code before Silex is initialized and set app[debug] = true after:
ini_set('display_errors', 1);
error_reporting(-1);
ErrorHandler::register();
if ('cli' !== php_sapi_name()) {
ExceptionHandler::register();
}
Tried to check the extent to which the code goes. But I was keeping on stepping in. I went till NativeSessionStorage::start() and gave up, so it was working till then and any errors I generate there were being reported properly as expected.
Tried looking at other entries for how to fix BSOD, but none of them really explained how things would have changed by moving from PHP 5.3 to PHP 5.4! That is ALL I did. Just changed the PHP version and PHP.INI accordingly. Below is the PHP.INI I use now.

I used the tools provided by the control panel of my hosting account to make the switch, so I am pretty sure it must be proper. I am able to run other PHP scripts.

I think I had the same problem before. If you are using PHP Version < 5.4.11 - there is a bug in the SessionHandler implementation - check this link out, maybe it is somehow related...
