[llvm-dev] Cross compiling an empty program results in a segfault

I'm trying to cross compile an empty program on macOS for Linux:

cat test.c

int main() {
        int a = 2+3;
        return 0;

clang -o -c -target x86_64-linux-gnu test.c

If I copy the resulting test.o to the Linux machine and run clang test.o,
it works fine.

However if I try to link it on macOS, I get a segfault when I launch ./a.out

ld.lld --entry main test.o

[copy a.out to Linux]

segmentation fault 0x00000000001 in ?? ()

Would really appreciate your help here!
