> Will this error message be enough or do I need to provide more information on the issue?

A reduced test case would be most helpful.

I assume it won't be trivial but I'll do my best to provide one soon.

Test case for #18015

I managed to eliminate the minimum code and it is surprising how small it is. To reproduce the corrupt output of DMD starting 2.075 run following commands:

> dub fetch vibe.d --version=0.7.32
> dmd -lib -debug -g -w -I~/.dub/packages/vibe-d-0.7.32/vibe-d/source configuration.d -vcolumns

To check the result of compilation I used:

> [[ $(nm configuration.a 2>&1 > /dev/null | grep "not recognized" | wc -l) -gt 0 ]] && echo "Compilation FAILS" || echo "Compilation OK"

Or, just using nm on the generated static library outputs to stderr that's something wrong. Running the test on 2.077 fails, on 2.074.1 succeeds.

The attachment is just:

  module arinas.platform.configuration;

  import vibe.data.json;

  static:

  Json defaultConfig;

Walter, the PR 6564 is definitively the cause, not just suspect.

May I ask, if this would be addressed any time soon, guys? I am really willing to help - if needed, however, the touched code in this PR is quite complex.

I cannot upgrade my platform built in D from version 2.074.1 to any of the more recent compiler versions because of this bug.

Hello guys,

if this is of any help, I found out, that commenting out
> align(8)
from before the definition of
> struct Json
in vibe.d's vibe.data.json module fixes the linkage.

Anyway, value of align(1,2,4) will just work; values from 8 through 128 break
the linkage.
