Description :
Using wp on the attached files, the rte-generated asserts (and some loop invariants) are reported as valid (green bullet), while they are dependent of some unproved loop invariant.
I flag it as WP bug, as it occurs only when specifying two provers with -wp-proof, so that I suspect some issue in reporting dependencies in this setting.
Steps To Reproduce :
command line used: frama-c-gui -wp -wp-model Typed+ref -wp-split binary_search_proved.c -wp-rte -wp-proof alt-ergo,why3:Z3
