Description :

When running the attached program, Jessie asked me to report a crash:

liveness_test.c:75:[jessie] failure: Unexpected failure. Please submit bug report (Ref. "interp.ml:994:8"). [kernel] The full backtrace is: Raised at file "src/kernel/log.ml", line 506, characters 30-31 Called from file "src/kernel/log.ml", line 500, characters 2-9 Re-raised at file "src/kernel/log.ml", line 503, characters 8-9 Called from file "src/lib/type.ml", line 746, characters 40-45 Called from file "queue.ml", line 134, characters 6-20 Called from file "src/kernel/boot.ml", line 50, characters 4-20 Called from file "src/kernel/cmdline.ml", line 170, characters 4-8

     Plug-in jessie aborted because of an internal error.
     Please report as 'crash' at http://bts.frama-c.com

It seems to be caused by the struct-type expression "hist[t]" in the loop-assigns clause in line 75. When I provide each struct-field by its own (see line 82; you can switch between both versions using the "#define" in line 3), Jessie works without problems.
