--- Comment #1 from Eduard Staniloiu <edi33416 at gmail.com> ---
Attempting to provide more context to this

Running `make -f posix.mak std/array.test`
will run
```
../dmd/generated/linux/release/64/dmd -od$T  -conf= -I../druntime/import  -w
-de -dip25 -m64 -fPIC -transition=complex -O -release -dip1000 -main -unittest
generated/linux/release/64/libphobos2.a -defaultlib= -debuglib= -L-ldl -cov
-run std/array.d
```

Where $T should expand to a path similar to `/tmp/.dmd-run-test.XXXXXX`

If you remove the `-cov` flag, the tests will build without any problem.

This issue is related with the Code coverage instrumentation
