:
1. httpd cought SIGPROF in free() because of `max_execution_time'
parameter.
2. php_error_cb() called free()
3. free() detected as `recursive call.'
in zend_mm_mem_malloc_free(), signal is blocked from
HANDLE_BLOCK_INTERRUPTIONS macro.
but, apache2handler does't have the function for it.
(gdb) p zend_block_interruptions
$1 = (void (*)(void)) 0
(gdb) p sapi_module
$2 = {name = 0x28759d5d "apache2handler", pretty_name = 0x28759d6c "Apache
2.0 Handler",
:
block_interruptions = 0, unblock_interruptions = 0,

(gdb) p apache2_sapi_module
$3 = {name = 0x28759d5d "apache2handler", pretty_name = 0x28759d6c "Apache
2.0 Handler",

:
in japanese mailing list, I got a patch for this problem.
