NOTE: I tried to post this on the DMD sub-board, but it gave me
and error and my post never appeared, so I'm putting it here
instead.
I've been working on this patch:
https://github.com/dlang/dmd/pull/6068
which fixes up some severe flaws in the inline assembler. But
I've hit a roadblock.
The patch is almost correct, everything *appears* to be working
as intended, except for this obscure bug that has somehow been
introduced as a side effect of the patch:
Makefile:205: recipe for target 'test_results/d_do_test.exe'
failed
gmake: *** [test_results/d_do_test.exe] Error 127
See my latest comment for details:

The problem is, I don't know where to start with debugging this.
I'm really struggling to envision how my patch could've caused
it. Even some basic suggestions or speculation would be much
appreciated.
This is my first time working on the DMD codebase, so I've been
discovering the details of its componentry along the way as I
diagnosed the bugs I encountered. Because this bug is manifesting
outside the compiler, I can't think of how I can trace it back to
its source.
Thanks for any help you can provide. I've been working hard on
this patch, so I really want to see it completed.
