Output from 'ldc -c tango/net/cluster/tina/CacheThread.d -oftest.bc'

A slightly modified ldc (to get it to cross compile for an arm target) running
on linux x86 gives the following error while compiling a file in the tango

ldc: TwoAddressInstructionPass.cpp:800: virtual
Assertion `TargetRegisterInfo::isVirtualRegister(regB) && "cannot update
physical register live information"' failed.
0   ldc 0x08add088
Stack dump:
0.      Running pass 'Two-Address instruction pass' on function
./build-tango.sh: line 110: 32166 Aborted                 (core dumped) $DC
Compilation of tango/net/cluster/tina/CacheThread.d failed

ldc is from hg, Mon May 04 13:32:16 2009 +0200, rev. 1299:847b767b2d0b,

tango is 0.99.8,

llvm is svn rev. 70630.

I couldn't get bugpoint to reduce the file size, so I attach the bitcode file
produced by ldc.

The error is reproducible by running 'llc -march=arm test.bc'.
