Hi folks,
There are 2 bugs that I'm trying to figure out. If you are
experiencing one of these bugs, can you post the version of sbcl
you're using (so far i've only seen it on sbcl), the version of clx,
and uname -a, and anything else that you feel is relevant? I want to
see if these errors only occur on certain architectures or certain
versions of sbcl or...something that ties them together.
Thanks!
1. modeline crash bug
The error is: Caught 'attempt to RETURN-FROM a block or GO to a tag that no
longer exists' at the top
And the meat of the backtrace looks like this:
7: ("foreign function: call_into_lisp")
8: ("foreign function: funcall2")
9: ("foreign function: interrupt_internal_error")
10: ("foreign function: handle_trap")
11: ("no debug information for frame")
12: (SIGNAL #<SB-SYS:MEMORY-FAULT-ERROR {B9F8899}>)
13: (ERROR SB-SYS:MEMORY-FAULT-ERROR)
14: (SB-SYS:MEMORY-FAULT-ERROR)
15: (SB-SYS:MEMORY-FAULT-ERROR)
16: ("foreign function: call_into_lisp")
17: ("foreign function: post_signal_tramp")
18: ((SB-PCL::FAST-METHOD REDRAW-MODE-LINE-FOR (T SCREEN))
2. stumpwm hang
There is no error, stumpwm just becomes unresponsive. The keyboard is
frozen to the point where switching to another console doesn't work
(control+alt+F1). Killing stumpwm unfreezes the keyboard. If you
manage to get a backtrace it looks like this:
1: (SB-SYS:INVOKE-INTERRUPTION #<CLOSURE (LAMBDA #) {49C8EAF5}>)
2: ("foreign function: call_into_lisp")
3: ("foreign function: funcall3")
4: ("foreign function: interrupt_handle_now")
5: ("foreign function: maybe_defer_handler")
6: ("bogus stack frame")
7: (SB-SYS:WAIT-UNTIL-FD-USABLE 5 :INPUT NIL)
8: (XLIB::BUFFER-INPUT-WAIT-DEFAULT
#<XLIB:DISPLAY :0 (The X.Org Foundation R60900000)>
NIL)
9: (XLIB::BUFFER-INPUT-WAIT
#<XLIB:DISPLAY :0 (The X.Org Foundation R60900000)>
NIL)
10: (XLIB::READ-INPUT
#<XLIB:DISPLAY :0 (The X.Org Foundation R60900000)>
NIL
NIL
#<FUNCTION (LAMBDA #) {49855D85}>)
11: (XLIB::READ-REPLY #<unavailable argument> #<unavailable argument>)
12: (XLIB:DISPLAY-FINISH-OUTPUT
#<XLIB:DISPLAY :0 (The X.Org Foundation R60900000)>)
13: (STUMPWM::STUMPWM-INTERNAL-LOOP)
14: (STUMPWM:STUMPWM ":0" NIL)
There are instructions on getting a backtrace for this bug here:
