+Summary: SIGSEGV on missing DLL
+
+Description of Problem:
+When an assembly references a DLL that cannot be loaded, the runtime
+crashes on a segmentation fault.
+
+Steps to reproduce the problem:
+1. echo 'class X{}' > a.cs
+2. gmcs /target:module /out:a.dll a.cs
+3. echo 'class Y{static void Main(){new X();}}' > b.cs
+4. gmcs /addmodule:a.dll b.cs
+5. rm a.dll
+6. mono b.exe
+
+Actual Results:
+=================================================================
+Got a SIGSEGV while executing native code. This usually indicates
+a fatal error in the mono runtime or one of the native libraries
+used by your application.
