Just a note on the essential types: the definition is in MISRA C:2012 Appendix D, but this definition is MISRA specific and not inherited from ISO C, so if an approach is taken to formulate rules on the basis of a system derived from the essential type system, then that type system would also need to be defined.

  *   Aaron
  *   Fulvio
  *   Roberto
  *   Clive

Charles reported contacting the ISO admin (Zoom account request) and following the news that the TS belongs to SC22 directly and not WG14, reached out to Chris Tandy (WG14 chair) for assistance

Roberto followed up on previous MISRA report:

  *   MISRA C11 updates fill be free
  *   updates will be in pieces, later rolled up (no target date)
  *   next full version will be C 2012 + TC
  *   major static analysis vendors are participating in the group
  *   Coverity hasn’t been heard from since they’re acquisition by Synopsis

Aaron (MISRA 11.7 / 12.4 follow up)

  *   int wraparound (WG14 is of the general view that there needs to be clarification)
  *   will check the pulse at Kona (18-23 Feb)


  *   we need a definition of “essential type”


  *   “essential type” is a term of art used by MISRA without definition

Clive (MISRA 13.1)

  *   side effect order is unspecified to be permissive or not
  *   ref MISRA 13.2
  *   need to harmonize the two
