This "only" supports my hypothesis that this is an issue with the
local name resolver. Maybe it helps to re-try this with libc6-dbg
installed, or to run exim under ltrace and/or valgrind. If that
doesn't give any conclusion, there is nothing to do short of running
exim under a debugger with a breakpoint set at readconf_main.

We're lucky that you can readily reproduce the crash. I cannot.
