@Walter this looks like it might possibly be the culprit.

https://github.com/dlang/dmd/blob/1c66d4303d298136a27b0ce4acd1f20ea31fe124/src/dmd/backend/dwarfdbginf.d#L1600-L1602

if (config.objfmt == OBJ_ELF)
    if (!sd.SDsym) // gdb ignores line number data without a DW_AT_name
        continue;
---

Is SDsym not being set for SCstatic functions?
