You're using EiffelStudio 6.2, right Chris?
I submitted bug report #14127 for a similar bug six weeks ago, with
EiffelStudio 6.2.7.2639. In my case, it's in a call to
EV_COMBO_BOX.set_strings, which has a precondition that calls
arrayed_list.for_all. The latter expects a function with a STRING_8
argument, but instead set_strings is passing a function with a
STRING_GENERAL argument.
Jocelyn mentioned to me that the most recent release has an option to
disable the runtime catcall checking under the Execution menu - Exceptions.
I haven't tried it yet.
This problem seems to arise from a combination of a few things:
1. They are trying to tighten up the catcall checking (which is undeniably a
good thing).
2. STRING was split into three classes back in EiffelStudio 5.7 (done for
the worthy cause of internationalisation, but I think everyone will be glad
when there is just one STRING class again).
3. The topsy-turvy conformance rules for agents may be contributing (and
even if they're not, they are sure helping to confuse me).
4. There's probably a bug in EV_COMBO_BOX.set_strings (but I'm not even sure
of that).
As it's been a month since the last 6.2 intermediate release, they've
probably resolved this by now ... fingers crossed :-)
