Anyway, installed and run it through valgrind, this is what I get when the
crash happens:

Seeing I'm not a C developer and can't really read valgrind's and gdb's
backtraces, you'll have to tell if this means anything. :)

OK, I am not able to make the vanilla version crash, but just now checked and
the production server is running manually compiled 5.2 version which also
crashes here (don't know if for same reason, assuming yes). I've taken their
./configure, but as it uses other, also manually compiled stuff, it doesn't
match my environment (and thus, also doesn't crash).
Are you able (by looking at the bt) to slightly reduce where this could be? I
can provide additional info and try/test stuff to see if it breaks. Also, as
said earlier, my co-worker got a crash on the exact same place, running Ubuntu.
When he gets back, I'll attach his BT here too.

Yeah, I need it to go through Apache to be able to access the URL which it
crashes on, seeing I don't have a simple script to run on a locally installed
executable.
I'm compiling vanilla as typing this, but have yet to figure out how to get the
exact ./configure from the RPM (different options might make it not crash at
all). The issue is that this is crashing on the exact same place on Fedora,
CentOS and Ubuntu (my co-worker tried) so my guess is that it isn't
distro-specific).
Will get back to you, tnx.

not really, best would be to be using our src directly. You don't have to
install
PHP, it can be done using a local install in your home.
If you can't do it, I would suggest to report the problem to fedora directly
but
without some kind of reproduce steps, there is little chance to get a fix.

If I recompile the RPM having disabled all the patches, does that count?

Please try using a plain vanilla php (from php.net)
