Description :

This entry references issue https://github.com/Frama-C/Frama-C-snapshot/issues/21 in order to be able to easily add files.

Steps To Reproduce :

Run the command

frama-c -pp-annot -no-unicode -wp -wp-rte -warn-unsigned-overflow -warn-unsigned-downcast -wp-model Typed+ref -wp-out rc.wp rc.c

on the attached files. As mentioned in the github issue, both 18.0 and 19.beta(2) report 17 VC of which 5 are discharged by Qed and the remaining 12 are verified by Alt-Ergo.

However, Frama-C 18.0 generates 12 .mlw and .out files, respectively. Frama-C 19 beta2, on the other hand, only generates 9 .mlw and .out files, respectively. The latter behaviour confuses our internal evaluation scripts which report that only 9 of the remaining 12 proof obligations have been discharged by Alt-Ergo.
