--- Comment #1 from moonlightsentinel@disroot.org ---
The failure occurs when compiling the unittests of the test tools `d_do_test.d`. The stack trace suggests that it's a a failure in the frontend which is quite surprising. Might be a memory corruption introduced by the GC given that the unittests are built with `-lowmem`.

Check whether -lowmem makes a difference, i.e. if the following succeeds:

dmd -m64 -fPIC -g -i -Itools -version=NoMain -unittest tools/d_do_test.d

Yes, your command succeeded. I was even able to run the resulting program and
got:
1 modules passed unittests

--- Comment #3 from Brian Callahan <bcallah@openbsd.org> ---
Further analysis suggests that using -lowmem immediately segfaults full stop no matter what you are compiling with dmd on 64-bit OpenBSD DMD.

I did not even think to check it because -lowmem works fine on 32-bit OpenBSD DMD. So this is a bug specifically on 64-bit OpenBSD DMD.

This ended up being a problem on my system, not a problem with DMD. Nothing needing fixing, DMD is working fine.
