Oops. Thank you for reporting this.

I fixed it for my upcoming submission.

In the meantime, you can replace "msg_safe" by "msg" in the rule
dedicated to the "report" mode.

That is

coccilib.report.print_report(p[0], msg_safe)

by 

coccilib.report.print_report(p[0], msg

The good point is that you only reach this point if Coccinelle has found
something to change in the code. So there is some patches to do... ;)
