Bitcode file to reproduce the bug with

Running bugpoint on the attached file gives several occurrences of the message
mentioned in summary. Run bugpoint with parameters "-mergereturn -loop-extract
-jump-threading picosat.bc". I did this on amd64, don't know if it happens on
32-bit llvm:

------------------------------------------------------------
$ bugpoint -mergereturn -loop-extract -jump-threading picosat.bc
Read input file      : 'picosat.bc'
*** All input ok
Running selected passes on program to test for crash: Whoops, an exception
leaked out of bugpoint.  This is a bug in bugpoint!
Exited with error code '1'

*** Debugging optimizer crash!
Checking to see if these passes crash: -mergereturn -loop-extract
-jump-threading: Whoops, an exception leaked out of bugpoint.  This is a bug in
bugpoint!
Exited with error code '1'
[...]

Ask me if you need the entire output from bugpoint.
