Thanks, that (the linker) solved it (I thought is was part of the 
gcc package). I just noticed meson tells me which linker is used. 
On AlmaLinux:

     D compiler for the host machine: ldc2 (llvm 1.28.0-git "LDC - 
the LLVM D compiler (1.28.0-git-5a28329):")
     D linker for the host machine: ldc2 ld.bfd 2.30-108

I downloaded and installed version 2.37 of binutils to match my 
Fedora system. Meson did not allow me to specify an absolute path 
to the linker, but putting it first in my PATH worked. With that 
the problems disappeared.


I very briefly tried v1.29 a little while ago, but my application 
compiled, started and then hung with 1.29. Haven't had time to 
isolate the problem area yet.


Would you have a pointer to information about "DSO registration" 
in ldc / D in general? Have only been able to piece together 
scraps of information so far, such as

     pragma(crt_constructor)
     // extern (C) routine here that starts the D runtime rt_init()
