Almost there. :) You tried to execute the php binary as a script, leave
that sapi/cli/php out of the last path, it's supposed to be the s.c.
top_srcdir. This should be correct for you:
# USE_ZEND_ALLOC=0 \
TEST_PHP_EXECUTABLE=/home/copacw/php5.2-200808110830/sapi/cli/php \
gdb --arg /home/copacw/php5.2-200808110830/sapi/cli/php -n \
run-tests.php -n /home/copacw/php5.2-200808110110830/
(gdb) run
<possible segfault>
(gdb) bt
Start copying the output of "bt" command from the line after the "run"
command which has the line with the crash info.

Output from gdb as follows. Is this what you were expecting? It
doesn't crash out, so there's no backtrace.
(gdb) run
Starting program: /home/copacw/php5.2-200808110830/sapi/cli/php -n

This should work:
# USE_ZEND_ALLOC=0 TEST_PHP_EXECUTABLE=/full/path/to/php \
gdb --arg /full/path/to/php -n /full/path/to/php \
run-tests.php -n /full/path/to/php/src/

When I compiled with
./configure --disable-all --enable-debug --with-pcre-regex
I can do a make test and it gets to the same place as before
(the cgi test) without core dumping. I then have to kill it
before it consumes the system memory.
You told me to run gdb as follows:
USE_ZEND_ALLOC=0 gdb sapi/cli/php -n run-tests.php
gdb wont accept such a command line, so I entered
run -n run-tests.php
from the gdb prompt and I then get the message:
Starting program: /home/copacw/php5.2-200808110830/sapi/cli/php -n
run-tests.php
ERROR: environment variable TEST_PHP_EXECUTABLE must be set to specify
PHP executable!
Program exited with code 01.
I've tried setting a TEST_PHP_EXECUTABLE environment variable to point
to the php executable, but I still get the same message.

Add the output of '(gdb) bt' here of the crash. Compile using this
configure line:
# ./configure --disable-all --enable-debug
Also, when you generate the backtrace, make sure you're not loading any
php.ini file using the '-n' parameter. f.e.
# USE_ZEND_ALLOC=0 gdb sapi/cli/php -n run-tests.php

I downloaded the latest this morning and did
./configure --disable-all
make test
I compiles okay and then still seg faults when it
gets to the test part of make test:
...
Build complete.
Don't forget to run 'make test'.
Segmentation Fault - core dumped
make: [test] Error 139 (ignored)
Same stuff as before from gdb:
#0 0x0010003c in _zval_ptr_dtor (zval_ptr=0x23f1e0)
at /home/copacw/php5.2-200808110830/Zend/zend_execute_API.c:412
412 (*zval_ptr)->refcount--;
(gdb) print *zval_ptr
$1 = (zval *) 0x1
(gdb)
I recompiled again with the DEBUG_ZEND=2 flag and got the following
result:
Build complete.
Don't forget to run 'make test'.

| ! ERROR ! |
| The test-suite requires that you have pcre extension |
| enabled. To enable this extension either compile your PHP |
| with --with-pcre-regex or if you've compiled pcre as a |
| shared module load it via php.ini. |
+-----------------------------------------------------------+
So reconfigured and recompiled again with --disbale-all
--with-pcre_regex. This time it compiled and got to test 3519 when
it again tried to spawn thousands of child processes. It
was in danger of consuming all available memory, so I killed
it at that point.
