Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc.
If possible, make the script source available online and provide
an URL to it here. Try avoid embedding huge scripts into the report.
Can you also include the libxml and libxslt versions you are using?

Description:
------------
PHP segfaults when shutting down. This appears to be the same symptom
as in bug #26384. I've included a backtrace, and some dumps of what
looked like the key structures.
Hope you can help,
Stu
Actual result:

At stack frame #2, I did some printing of the xmlNodePtr node. I don't
know if this is useful or not.
(gdb) print *node->parent->parent
$8 = {_private = 0x864e288, type = XML_ELEMENT_NODE,
name = 0x84c1250 "\030ăd\bicontent", children = 0x84c7418,
last = 0x864e290, parent = 0x84b2778, next = 0x0, prev = 0x84c11d8,
doc = 0x850db48, ns = 0x0, content = 0x0, properties = 0x0, nsDef =
0x0,
psvi = 0x0, line = 0, extra = 0}
(gdb) print *node->parent->parent->parent
$9 = {_private = 0x0, type = XML_ELEMENT_NODE, name = 0x84c1268
"Module",
children = 0x84c11d8, last = 0x84c73d8, parent = 0x84a68d8,
next = 0x84c12a8, prev = 0x84ab0b0, doc = 0x850db48, ns = 0x0,
content = 0x0, properties = 0x84c1218, nsDef = 0x0, psvi = 0x0, line
= 0,
extra = 0}
(gdb) print *node->parent->parent->parent->parent
$10 = {_private = 0x0, type = XML_ELEMENT_NODE, name = 0x84a6918
"Modules",
children = 0x84ac800, last = 0x84c12a8, parent = 0x850dc48, next =
0x0,
prev = 0x84b32b8, doc = 0x850db48, ns = 0x0, content = 0x0,
properties = 0x0, nsDef = 0x0, psvi = 0x0, line = 0, extra = 0}
(gdb) print *node->parent->parent->parent->parent->Parent
There is no member named Parent.
(gdb) print *node->parent->parent->parent->parent->parent
$11 = {_private = 0x0, type = XML_ELEMENT_NODE, name = 0x8304bc8
"XmlOutput",
children = 0x81e69f8, last = 0x84a68d8, parent = 0x850db48, next =
0x0,
prev = 0x0, doc = 0x850db48, ns = 0x0, content = 0x0, properties =
0x0,
nsDef = 0x0, psvi = 0x0, line = 0, extra = 0}
And, from stack frame #1, here's a print of zval * wrapper:
(gdb) print *wrapper
$12 = {value = {lval = 800, dval = 1.3580773101702994e-312, str = {
val = 0x320 <Address 0x320 out of bounds>, len = 64}, ht =
0x320,
obj = {ce = 0x320, properties = 0x40}}, type = 112 'p',
is_ref = 23 '\027', refcount = 2136}
