You mention you're using Docker. https://github.com/moby/moby/issues/11740 has some info on how to generate core files inside a Docker container. You should be able to load that up in gdb and see exactly what's going on.

Latest LDC (1.4.0) gives you AddressSanitizer which can catch bad memory accesses and reports them in a nice way. Use `-fsanitize=address` when compiling. Caveat: it doesn't catch memory bugs involving GC-(de)allocated memory yet (only _very_ bad ones). But it does catch malloc'ed memory bugs and stack bugs.

That the xml experimental library is now abandoned by the author? Not much hope there

my dom.d works :P

Thank you all. In the meantime I found the cause: At one point in the code, null was used as a key in a map i.e. associative array.

It is really great that D has such a great community.
