Bug Type: Compile Failure
Operating System: Solaris 9
PHP Version: 5.2.6

New Comment:
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 |

| 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.

Get this:
http://snaps.php.net/php5.2-latest.tar.gz
And do not apply any 3rd party options. And do (exactly) this:
# ./configure --disable-all && make test

Description:
------------
'make test' fails immediately with a segmentation fault. Re-compiling
with compiler flag DEBUG_ZEND=2 allows 'make test' to get to test
4399 before spawning several thousand php-cgi children and consuming
all
the system memory.
Actual result:
--------------
Initial configure command was:
env LDFLAGS="-R/copac/gcc-4/lib" ./configure --prefix=~/apache-
2_2/ --with-mysql=/home/copacw/mysql5/mysql --with-libxml-
dir=/home/copacw/apache-2_2
A 'make test' from the above results in this:
huntly copacw/php-5.2.6 $ make test
Build complete.
Don't forget to run 'make test'.
Segmentation Fault - core dumped
make: [test] Error 139 (ignored)
A backtrace of the core file from the above:
#0 0x00220130 in _zval_ptr_dtor (zval_ptr=0x39d8a8)
at /home/copacw/php-5.2.6/Zend?/zend_execute_API.c:412
412 (*zval_ptr)->refcount--;
(gdb) list
407 ZEND_API void _zval_ptr_dtor(zval **zval_ptr
ZEND_FILE_LINE_DC)
408 {
409 #if DEBUG_ZEND>=2
410 printf("Reducing refcount for %x (%x): %d->%d\n",
*zval_ptr, zval_ptr, (*zval_ptr)->refcount, (*zval_ptr)-
>refcount-1);
411 #endif
412 (*zval_ptr)->refcount--;
413 if ((*zval_ptr)->refcount==0) {
414 zval_dtor(*zval_ptr);
415 safe_free_zval_ptr_rel(*zval_ptr
ZEND_FILE_LINE_RELAY_CC ZEND_FILE_LINE_CC);
416 } else if ((*zval_ptr)->refcount == 1) {
(gdb) print *zval_ptr
$1 = (zval *) 0x1
I reconfigured by adding CFLAGS="-DDEBUG_ZEND=2" to the start of the
configure command, did a 'make clean', then 'make', then
'make test'.
This time the 'make test' gets to test 4399 and then fails as below:
....

TEST 4399/4426 [sapi/cgi/tests/001.phpt]
Test 4399 spawned over 4400 php-cgi child processes (on a previous run
when I left it
to its own devices it kept going until it had consumed all the system
memory and swap.)
A ps of the process it created is as follows:
$ ps -ef | grep php-cgi
copacw 40 37 0 12:22:05 pts/3 0:00 sh -c
/home/copacw/php-5.2.6/sapi/cgi/php-cgi -n -v
copacw 29989 29988 0 12:22:03 pts/3 0:00 /home/copacw/php-
5.2.6/sapi/cgi/php-cgi -n -v
copacw 1721 1720 0 12:23:07 pts/3 0:00 /home/copacw/php-
5.2.6/sapi/cgi/php-cgi -n -v
...
I also tried 'make install'. The first compile WITHOUT the DEBUG_ZEND
flag failed
on a 'make install' with a segmentation fault. The compile WITH the
flag successfully
performed the 'make install'.
