Description:

because in PHP exit is implements by set/longjmp



so the normal sequence 



php_stream_wrapper_log_error

php_stream_display_wrapper_errors

  -> php_error_docref1

php_stream_tidy_wrapper_error_log



when use set_error_handler,  and call exit in use_handler, 

cause the php_stream_tidy_wrapper_error_log to be miss called,



which cause wrap->err_count doesn't reset to zero after request
shutdown.



then cause the following code coredump in
php_stream_display_wrapper_errors



 for (i = 0, l = 0; i < wrapper->err_count; i++) {

l += strlen(wrapper->err_stack[i]); //core

if (i < wrapper->err_count - 1) {

l += brlen;

}

}

Test script:
---
http://unreachable.com/ServiceNoWse.asmx?WSDL";);

Expected result:

normal exit

Actual result:
--
core dump
