[ruby-core:97736] [Ruby master Bug#16765] Crash when use sass image-url in email layout

Issue #16765 has been updated by jeremyevans0 (Jeremy Evans).

Status changed from Open to Feedback

Unfortunately, the crash report does not provide the relevant debugging information:

```
Thread 22 Crashed:: thread_pool.rb*

6   libsystem_platform.dylib      	0x00007fff6cddd5fd _sigtramp + 29
```

It does appear to be a null pointer dereference:

```
Exception Type:        EXC_BAD_ACCESS (SIGABRT)
Exception Codes:       KERN_INVALID_ADDRESS at 0x0000000000000000
```

While there isn't much to go by, it seems likely to be a bug in sassc.  There are other null pointer dereference bugs on their issue tracker already: https://github.com/sass/sassc-ruby/issues

Can you reproduce this issue without sassc?
