Description Iain Buclaw 2021-11-23 01:05:50 UTC 
static int func();

int main()
{
  return func();
}

static int func()
{
  return 0;
}

Looking at the output of nm, you can see the function appears twice.

0000000000000000 t func
                 U func
0000000000000000 W main

Fixed by https://github.com/dlang/dmd/pull/13399
Comment 3 Andrea Fontana 2022-04-08 10:18:27 UTC 
The same code using -lib won't work:

dmd file.c -lib

Error: no definition for static func
Comment 4 duser 2022-04-21 14:42:33 UTC 
it works with -lib on stable v2.099.1 but not current git master

bisected it to https://github.com/dlang/dmd/pull/13846

Please don't reopen fixed bugs with different bugs. It makes the bug list unnecessarily hard to manage.
