That sounds like a bug:
dmd -shared -oflibfun.dylib fun #WOULD WORK with -lib instead of -shared
dmd -g -L-L. main
./main #SEGFAULTS... see lldb output below
//main.d:
import std.stdio;
pragma(lib,"fun");
void main(){
writeln();
}
//fun.d:
//import std.stdio; //UNCOMMENT THIS LINE TO MAKE IT WORK ...
extern(C)
int parse(int x){return x;}
--------------------------------
output of lldb:
