During unittest in my own fork of std.experimental.xml (link: 
https://github.com/ZILtoid1991/experimental.xml ), potentially an 
error so severe is present, that it causes to crash the compiler 
(both DMD and LDC2, on Windows). I was able to separate the issue 
by commenting out all unittests, then re-enabling them one-by-one 
seeing when it crashes the compiler, but wasn't able to track 
down the issues. However, `domimpl.d` is a 2000+ line monster, 
with a huge templated class that nests multiple other classes. I 
suspect that there's some leftover from the stripped configurable 
allocator and/or error handler, that causes the issue.

At worst-case scenario, I can just manually rewrite the whole 
part (I already planned to write a more linear cursor for speed 
reasons), but that will consume a lot of my time. A lot of part 
of the code is already undocumented (especially anything 
non-public), so it's a question whether reimplementing stuff from 
almost zero, or trying to decipher a legacy code is the easier 
stuff.

You may be able to use dustmite to automatically reduce the code 
to a minimal test case:

What do I pass as the tester?

I tried to compile on the Raspberry Pi 400, now I'm getting 
segmentation fault during compilation with LDC. Still no idea 
what causes it, nor how to reduce it. Moved the codebase to a new 
repository, gave it a proper DOMString implementation instead of 
using it as a template name, and I'm still getting no luck 
compiling it. Current link: https://github.com/ZILtoid1991/newxml

I might try to comment out the bodies of the functions and force 
them to return an initial value, to see if there's something 
wrong with the insides of the functions.
