I have found the bug. init_heap_seg was using SCM_SET_CELL_TYPE to initialize fresh memory to 'free cells', but with DEBUG_CELL_ACCESSES, SCM_SET_CELL_TYPE could run a GC, which might see the half initialized heap segment during conservative scanning and would access uninitialozed memory which caused it to fail. I have fixed this by using the new macro SCM_SET_FREE_CELL_TYPE, which does no checking. _______________________________________________ Bug-guile mailing list [EMAIL PROTECTED] http://lists.gnu.org/mailman/listinfo/bug-guile
