6442502: assert(bits,"Use TypePtr for NULL") on linux-x86 Reviewed-by: This is part of a family of bugs that occur when linux happens to place the card table and the heap at locations such that the byte_map_base ends up being NULL. The fix is to handle this case specially and to unify the logic for getting a Node to represent the byte_map_base instead of replicating the logic. tested with runthese sparc/x86 32/64 bit |
