New Comment:
Sigh.
Since my entire post of 10/11 Nov has been deleted, and I did not
receive an e-mail copy of my post via the bug submission system, I have
no record of what I said. Presumably I stated that I, too, had
encountered the problem, that I couldn't even install PHP 4.3, that it
was due to int/long size mismatches on LP64 platforms, and then
indicated the strategy I had used to work around it (via patches).
I posted patches and test result information (for HEAD of the day and
also for 4.3.0pre2) to php-dev on 11 November 2002. Thread subject was
"64-bit PHP 4.3 (extensive long vs int problems)". Those patches are
now out of date because (on the downside) further int/long problems
have crept in and (on the upside) some test cases have been improved.

PLEASE do NOT add such long diffs to bug reports!
Instead put them on some site and add an URL to them here.
(I deleted those comments from here now since they're pretty useless as
the bug system mangles them anyway)

Forgot to mention - bug 21822 has the same root cause as this one.

I am glad to see someone is looking at the OnUpDateInt issue, and I
think adding an OnUpdateLong is a good way to go. On Tru64 the int* vs.
long* can cause some really hard to track errors because if the storage
area is an int and is treated as a long, 32 bits of data following the
int gets scrubbed with apparently no reason. I dug through a bunch of
the 4.3.1 code and there is quite a mix of int an long being passed to
OnUpdateInt, either directly or indirectly as in the case of zlib
(which is where I encountered it). Blindly changeing OnUpdateInt to use
int* will not work as there are quite a few longs being passed into the
routine.
The right answer seems to be adding OnUpdateLong and then doing a code
sweep of the core and extensions to make sure the right one is called,
which seems to be the thrust of the previous response. I hope these
changes will show up in the mainstream soon.
thanks!

The CVS version (and the 4.3.0pre2 version, same error and backtrace)
core dumps on startup with this error:
