It faults on this code in druntime/src/rt/lifetime.d:
==================================
// we expect this to be called with the lock in place
extern(C) void rt_processGCMarks(void[] tls)
{
    // called after the mark routine to eliminate block cache data when it
    // might be ready to sweep

    debug(PRINTF) printf("processing GC Marks, %x\n", tls.ptr);
    auto cache = *cast(BlkInfo **)(tls.ptr + __blkcache_offset);
                                   ^^^^^^^^^^^^^^^^^^^^^^^^^^^
=================================
Both tls.ptr and __blkcache_offset are NULL.
