…ause the dependency graph to fail.

Good catch! Would it be possible to add a test? Likely that test just needs to use —show-dependence-graph. |

Looks good please add the original regression test and this should be good to merge. The equivalent PR against develop would also be useful. |

There was a problem hiding this comment.
I don't think this change is necessary, the cases of renamed functions should all be caught above.

Apologies for the merge while commenting. The goto-analyze-develop branch will hopefully soon be gone in favour of moving stuff into master so as long as it is fixed in #1677, all should be well. |

Before this patch, two static functions with the same name but in different files would cause
goto-analyzerto fail with an assertion violation:The problem was that one of these two clashing functions had its symbol renamed (added a
$link1postfix to its name), but the corresponding instructions of the function were not getting updated accordingly (instructionts contain a field calledfunction, which is anirep_idtreferring to the function that the instruction belongs to).Pinging @martin-cs and @chrisr-diffblue for review.
