This seems to be a bug in GDC since it happens on only this one
platform and net searching says that GCC has had problems with symbol
interpositioning in the past. This is easy to replicate without Meson.
Write this code to source.d:

import std.stdio;
import utils;
import std.string : format;

void printGreeting (string name)
{
writeln ("Hello, I am %s.".format (name));
}

void main ()
{
printGreeting ("a Meson D test");
}

Compiling it with 'gdc -o prog source.d' gives the same error.
Removing the string formatting portion makes it work again as does
compiling with -fPIC, but if that is somehow always needed GDC should
either add -fPIC itself, error out earlier or, at the very least,
print a more relevant error message. LDC compiles this same program
without errors without needing -fPIC.

If this issue is in GDC and it is not fixed until the next release,
Meson will fix the issue by changing the build dep from gdc to ldc.

Thanks,

Hi,

During a rebuild of all packages in sid, your package failed to build on
amd64.

About the archive rebuild: The rebuild was done on EC2 VM instances from
Amazon Web Services, using a clean, minimal and up-to-date chroot. Every
failed build was retried once to eliminate random failures.
