Not sure it's the same bug since mine triggers a stack overflow with no
diagnostics.  Here's the dustmite script I used to reduce:

#!/bin/sh

# arguments to dmd
DMDARGS="test20719.d"

OUTPUT=$(lldb --batch -o "run $DMDARGS" -k 'bt 30' -k 'quit' -o 'quit' dmd
2>&1)
#echo $OUTPUT
echo "$OUTPUT" | egrep -q
"_D3dmd4func15FuncDeclaration14isTypeIsolatedMFCQBt5mtype4TypeZb" 
exit $?
