--- Comment #3 from Tomoya Tanjo <ttanjo at gmail.com> ---
I close this issue because it is a matter of linker options rather than
druntime itself.
It only happens when using `gcc` on Alpine Linux.
It does not happen when using `clang`.

When we use `gcc` as a linker, it needs `-Xlinker --eh-frame-hdr`.
```console
$ dmd -c app.d
$ gcc app.o -o app -m64 -static -Xlinker --eh-frame-hdr -Xlinker
--export-dynamic -L/usr/lib/ -Xlinker -Bstatic -lphobos2 -lpthread -lm -lrt
-ldl -lunwind
$ echo $?
0
```

When we use `clang` as a linker, it works without `-Xlinker --eh-frame-hdr`
because `clang` implicitly passes them to `ld`.
```console
$ dmd -c app.d
$ clang app.o -o app -m64 -static -Xlinker --export-dynamic -L/usr/lib/
-Xlinker -Bstatic -lphobos2 -lpthread -lm -lrt -ldl -lunwind
$ ./app
$ echo $?
0
```
