<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">In the relevant CALL_MMAP in src/lj_alloc.c, luajit tries to mmap at a specific address (MMAP_REGION_START). It then checks whether the address returned by mmap() is between MMAP_REGION_START and MMAP_REGION_END. If it isn't, it fails.<br>
<br>
However, our mmap() will not try to actually allocate at the passed address without MAP_TRYFIXED (for right or wrong - haven't looked at our mmap yet). Adding MAP_TRYFIXED to the MMAP_FLAGS solves the problem and luajit starts up.<br>

Can you provide a ktrace(1) output? Just ktrace luajit, and then<br>
kdump and get the output.<br>

It looks like it's trying something specific; assuming it's really<br>
not supported on DragonFly, you could look in the file and see if it<br>
has a fallback for other operating systems that don't support this<br>
feature and add DragonFly to that fallback.<br>
