Hi Coccinelle developers,


When I was working on my patch, I was hit by another issue.

badzero.cocci failed on all modes.


Can you take a look at it, please?



I tried to use DEBUG_FILE and dump the log,
but I could not get a clue of the cause of the failure.

My spatch version is:
spatch version 1.0.6-00345-g2ca0bef compiled with OCaml version 4.02.3




The following is the result on my PC:


$ make  coccicheck  COCCI=scripts/coccinelle/null/badzero.cocci  MODE=report
