Andy Wingo 17d1b4bffd fix stack corruption on vm-save-stack; more robust with nonlocal exits ... * module/system/repl/command.scm: Coerce rationals to floats. * module/system/vm/program.scm (program-documentation): Fix a typo, doh! * src/vm.c (vm_reset_stack, struct vm_unwind_data): Add unwind handler to reset vp->sp, vp->fp, and vp->this_frame when performing a nonlocal exit from a vm_run. (vm_heapify_frames_1): Don't repack the stack, it causes stack corruption. I think we need spaghetti stacks to handle continuations, not separate heap frames. I don't think call/cc is working now. (vm-save-stack): Don't call heapify_frames, that modifies the stack that we're copying. Instead call its helper, heapify_1. * src/vm_engine.c (vm_run): Set up the vm_reset_stack unwind handler. * src/vm_engine.h (IP_REG, SP_REG, FP_REG): If we got through all of the checks without having these macros defined, define them as empty. Happens on x86-64. * src/vm_system.c (halt): End the dynwind before we return from the VM. * src/vm_scheme.c (REL): Sync the regs before calling scm_lt_p et al, cause they can do a nonlocal exit.		2008-08-07 19:04:25 +02:00
