Package: sbcl Version: 1:1.0.18.0-2 Severity: normal Sometimes (TIME x) prints #\0 endlessly. It looks like the condition is when the evaluation of x takes a whole number of wall-clock seconds greater than 1 (+/- 1ms).
Examples (Ctrl+C successfully interrupts SBCL): sbcl --noinform --eval '(time (sleep 2))' --eval '(sb-ext:quit)' sbcl --noinform --eval '(time (sleep 9))' --eval '(sb-ext:quit)' If you don't see the problem, it's probably because SLEEP took e.g. 2.001 seconds instead of 2.000. Keep trying. Other cases of (TIME (SLEEP n)), where n is 0, 1 or not an integer, don't suffer from the same problem. It looks like the implementation of TIME uses FORMAT-MILLISECONDS, which suffers from the same problem. I tried finding the bug in %FORMAT-DECIMAL (called by FORMAT-MILLISECONDS), but it looks like the loop it's getting caught in (the one in the %ZEROES local function) should terminate in all cases, so I couldn't pinpoint the error. (SB-IMPL::FORMAT-MILLISECONDS *standard-output* 2001 nil nil) >> 2.001 seconds => " seconds" (SB-IMPL::FORMAT-MILLISECONDS *standard-output* 2000 nil nil) >> 2.0000000000000... => (doesn't return) Thanks for taking a look at this, -- System Information: Debian Release: 5.0.3 APT prefers stable APT policy: (700, 'stable'), (650, 'testing') Architecture: i386 (i686) Kernel: Linux 2.6.26-2-686 (SMP w/1 CPU core) Locale: LANG=C, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages sbcl depends on: ii common-lisp-controller 6.17 Common Lisp source and compiler ma ii libc6 2.9-25 GNU C Library: Shared libraries Versions of packages sbcl recommends: pn binfmt-support <none> (no description available) Versions of packages sbcl suggests: pn sbcl-doc <none> (no description available) pn sbcl-source <none> (no description available) ii slime 1:20080223.dfsg-1 Superior LISP Interaction Mode for -- no debconf information -- J.P.
