Subject: Fix a NULL-ptr deref

```
Program terminated with signal SIGSEGV, Segmentation fault.
20	  if (!(func->common.function_name)) {
(gdb) info locals
func = 0x0
function_name = 0xffb25f6d0190 "SearchByCallback"
complete_path_function = 0xffb26c8a0570 "\240\005\212l\262\377"
```

It seems that in some callback shenanigans, there is currently no non-NULL
`func` member in execute_data. PHP truly is marvelous.

This should close #515
