Good catch.
It's almost certainly the error handler.
However, while I try to paste the code here, this broken bugtracker keeps
rejecting it as spam.

I really doubt this is crashing PHP. I would have a look at any custom error
handler you have in place and look at what it does with Illegal Offset
warnings.
This is a new warning in PHP 5.4 which you get if you try to use a string as if
it was an associative array, since this is what you are doing in this case.

SUPER LOL
What is triggering the crash is this code:
$info="SELECT offset,height FROM segment ORDER BY id DESC limit 1";
$offset=$info['offset']+$info['height'];
Obviously the code is screwed up (I use the query string as if it was the
result
from a query!!) but it's crashing PHP instead of triggering an error.
Curiously enough, though, this only happens inside the true intricated code and
not if isolated.
Anyway I can 100% assure these are the lines of code that trigger the crash

It seems too damn complicated to get a backtrace.
Php (and any program for that matter) should be built in such a way that if it
crashes, there would be a file somewhere ready to pick!

Apparently my php is configured with --disable-debug.
How do I get a debug-enabled version?

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32
Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.
