This works independently + of --gc-debug. + + * gc.c (opt_vg_debug): New conditionally defined global variable. + (more): Mark entire heap of free blocks inaccessible, if + vg debugging is enabled. + (make_obj): If vg debugging enabled, mark returned block as accessible, + but undefined, and take care to grant self temporary access while + manipulating the free list. + (finalize): Removed old debugging logic of not freeing strings + and vectors during gc debug. If the null pointers are ever a problem + during debugging, they can be checked inside obj_print, and + turned into #<garbage ...> notation. + (sweep): Switch to FIFO free block recycling if vg debugging is + enabled, just like when gc debugging is enabled. + Mark freed blocks as inaccessible, careful to grant self + temporary access while manipulating the free list. + + * txr.c (txr_main): Parse the --vg-debug option. + + * txr.h (opt_vg_debug): Conditionally declared. + +2009-11-25 Kaz Kylheku <kkylheku@gmail.com> + Fix a build breakage that may happen on some platforms.
