Virtual Machine

• 2015-05-21
  • Use mmap() / munmap() to allocate new space.
  • When VM is compiled in DEBUG mode (default), allocate extra guard pages behind each newspace halve.
  • Fixed baaad bugs in various allocation routines causing overflow to memory behind newspace and thus trashing whatever data are there. See commit ​384622fa1a79, few VM routines suffered the same.
  • Fixed initialization of poly caches (they have not been cleared properly)
