Bug Type: Bug
Bug description:SegFault
Description:
------------
Apache process crashes with a segfault. Was able to narrow it down to
zend_vm_execute.h line 580 using the backtrace. Looks like
fbc->common.fn_flags
in the code is causing the issue.
if (UNEXPECTED((fbc->common.fn_flags &
(ZEND_ACC_ABSTRACT|ZEND_ACC_DEPRECATED))
!= 0)) {
if (UNEXPECTED((fbc->common.fn_flags & ZEND_ACC_ABSTRACT)
!= 0))
{
zend_error_noreturn(E_ERROR, "Cannot call abstract
method %s::%s()", fbc->common.scope->name, fbc->common.function_name);
CHECK_EXCEPTION();
ZEND_VM_NEXT_OPCODE();
}
if (UNEXPECTED((fbc->common.fn_flags & ZEND_ACC_DEPRECATED)
!=
0)) {
zend_error(E_DEPRECATED, "Function %s%s%s() is
deprecated",
fbc->common.scope ? fbc->common.scope->name
:
"",
fbc->common.scope ? "::" : "",
fbc->common.function_name);
}
}
Actual result:
--------------
Program received signal SIGSEGV, Segmentation fault.
