they are trying to be smart and using a LINUX procfs feature that we don't support. probably trying to find out something about their command line.. (what an odd idea what's wrong with argv/argc?) probably due to this failure, they are leaping off into space and doing an illegal memory reference. To their credit, they are trapping that, cleaning up and sending themselves a signal to force a core-dump. probably JUSTRETURN may not be the best return value, as the program may not realise it had an error. try truss, as that gives better information under linux emulation I'm told.
