Killed

Strace shows the program sitting in some kind of tight loop,
including:

select(2, [], [1], NULL, {0, 0})        = 1 (out [1], left {0, 0})
write(1, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"...,
8096) = ? ERESTARTSYS (To be restarted if SA_RESTART is set)

+++ killed by SIGKILL +++

I'm unclear why it gets a SIGKILL; it does not seem to run out of memory.

The brainfuck program was generated using brainfuck-monad,
with this haskell code.

cat = brainfuckConstants 1 $ flip forever $ input >> output

AFAICs that should just print to stdout what's read from stdin.

The program works when run in beef(1).

Hi Joey,

thanks for your report. According to
http://hackage.haskell.org/package/brainfuck
hsbrainfuck is unmaintained, so there is probably not much going to
happen about this (besides, maybe, the removal of this package from
Debian).

Greetings,
Joachim
