One thing that bugged me for years in D is how difficult it is

What version of compiler/runtime are you using? I've fixed this
behaviour
(fatal error if no exception handler is found) in v2.076:
https://github.com/dlang/druntime/pull/1673 and the fix should
actually
call abort():

Judging from the output (dwarfeh(224) fatal error), this patch
is not applied
in your runtime.
As for the core dump - the runtime actually calls abort (pre and
post my patch, as it looks like). I'm not aware anything in the
runtime handling SIGABRT, are you doing it in your application?
Is your system setup to generate core files `ulimit -c unlimited`
or similar? You should at least get in your stderr (not stdout)
message that the SIGABRT was raised (and you did before IIRC,
you've commented it on one PR).
