This happens because config test does not shutdown SAPI.
In addition this commit also fixes few failures when running FPM tests
under root.
Closes GH-10296
When the validation logic for param->type was added, the logic did not
account for the case where param could be NULL. The existing code did
take that into account as can be seen in the `if (param)` check below.
Furthermore, phpdbg_set_breakpoint_expression even calls
phpdbg_create_conditional_break with param == NULL.
Fix it by placing the validation logic inside a NULL check.
If zend_register_module_ex were to return NULL, then module_entry will
be set to NULL, and the if's body will load module_entry->name. Since
module_entry is NULL, loading the name would cause a NULL pointer
dereference. However, since a NULL pointer dereference is undefined
behaviour, the compiler is free to remove the check.
Fix it by using *name instead of module_entry->name.

The check checks whether p is non-NULL. But if it were NULL the function
would crash in later code, so the check is useless.
It seems like *p was intended, but that is redundant as well because
isspace would return false on '\0'.
`ap_get_brigade()` may fail for different reasons, and we must not
pretend that a partially read POST payload is fine; instead we report
a content length of zero what matches all other `read_post()` callbacks
of bundled SAPIs.
Closes GH-10059.
The code checks if stack is a NULL pointer. Below that if the
stack->next pointer is updated unconditionally. Therefore a call with a
NULL pointer will crash, even though the if (stack) check seems to show
the intent that it is valid to call the function with NULL.
The function is not meant to be called with NULL, so just ZEND_ASSERT
instead.
There might be a moment when the child log event is executed after
freeing a child. That could possibly happen if the child output is
triggered at the same as the terminating of the child. Then the output
event could be potentially processed after the terminating event which
would cause this kind of issue.
The issue might got more visible after introducing the log_stream on
a child because it is more likely that this cannot be dereferenced
after free. However it is very hard to reproduce this issue so there
is no test for this.
The fix basically prevents passing a child pointer and instead passes
the child PID and then looks the child up by the PID when it is being
processed. This is obviously slower but it is a safe way to do it and
the slow down should not be hopefully visible in a way that it would
overload a master process.
