@MoonlightSentinel created dlang/dmd pull request #13895 "Fix 22489 - dtoh:
Handle custom mangling for functions (and globals)" fixing this issue:

- Fix 22489 - dtoh: Handle custom mangling for functions (and globals)

  Explicit mangling provided via `pragma(mangle, "..")` cannot be mapped
  to C++. For `extern(C)` function it's possible to emulate the behavior
  by replacing the identifier with the custom mangling. This doesn't work
  for `extern(C++)` functions, so they are ignored.

  The same rationale + solution applies to global variables with custom
  mangling.
