+I've played around with mono/metadata/appdomain.c a bit.
+'make_shadow_copy' (which was introduced in r64262) tries to create a
+temporary file using 'mono_mkstemp'. The pathname is assembled by
+'g_build_filename' which accepts a base and a NULL terminated list of
+path components. The base is the DynamicBase of the Mono domain
+(domain->setup->dynamic_base). Because string is NULL (at least the
+return value of 'mono_string_to_utf8') 'g_build_filename' also returns
+NULL. This is why mono_mkstemp fails!
+Is it the DynamicBase which is not initialized correctly? Is it
+ignored when creating new domains? Can it be configured somewhere? I
+actually don't know and do not have the time to investigate any further.
+Could anybody please have a look what is going wrong there? Would be
+great! I currently can only use the Mono environment here with a very
+ugly patch.
