I removed dlmalloc...I will try to compile it under Linux as soon as 
possible.
I'm mystified by what's happening because when I changed main to:
_page*a_page=new _page;
I got the segfault again even when the _page::operator new had:
void*p=
     #if 0
       _CPPGC_MALLOC(gc::_mem_space, size);
     #else
       0;
     #endif
???
OOPS.  Maybe because a _page cannot be constructed at location 0 :)
Anyway, I tried running with:

   void*p=::operator new(size);

and it worked, then tried with src/main.cpp but it never terminated
until I manually aborted.

Hope you can get the unix working soon.

Good luck!
