Excellent! I can reproduce it.
The D2 version of this code (char[] text = `Hi`.dup;) segfaults in 
Expression::arraySyntaxCopy() in expression.c, with evidence of memory 
corruption. The D1 version does *not* segfault there. In fact the code 
compiles with the debug version of DMD1!
I think the array literal isn't getting initialized properly.
