wolfram,
Could you locate which line is causing following error?
"Unsupported operand types in Unknown on line 0"
I don't get this error message with my applicatins.
Are you using any cache products?

After applying the patch above, my Apache segfaults on scripts which
ran fine before or just prints "Unsupported operand types in Unknown on
line 0". Using PHP 4.2.0RC1.

Increasing the refcount width from short to long doesn't
solve the issue. A strict upper limit test is badly needed
to check whether the refcounter can be increased in the
given limit or not.
I suggest to throw a memory exhausted error with a hint
that no more reference counters could be allocated.

This should be refcount issue.
Change _zval_struct's refcount data type from unsingned short to
unsinged int, then PHP should be fine upto 4G.
Without patch refcount can be upto 64K and no error check
is done -> segfualts.
ZE2 is changed to use unsinged int already. IIRC.

I did the same test on my machine (Linux 2.4.18, PHP 4.1.2
CGI-Version).
My php.ini looks like this:
memory_limit = 8M
log_errors = On
error_log = syslog
When I run the test routine nothing appears in my syslog and I get the
segfault.
