In the attached code, the struct's internal data is modified by lli when
--force-interpreter flag is specified while it is correctly not modified
without the flag.

$ lli -force-interpreter code.s.bc
checksum x.A = 0
checksum x.B = 0
checksum x.C = 2

$ lli code.s.bc
checksum x.A = 0
checksum x.B = 0
checksum x.C = 1

This code is compiled with llvm-2.7's version of dragonegg and run with
