Some problems on the SPOJ can only be solved in Brainf**k using the bff interpreter. I keep getting some errors with codes i think that are right. for example:
this code:
,[->,+]<[.<]
run with this input:
asdf
works properly on the bff generating the output:
fds`
while this one:
,+[->,+]<[.<]
running with the same input prints on stderr the message: "bff: out of memory (985548044)"
I have downloaded the bff version 1.0.3.1 (which is the one at spoj) and run examples in my computer, getting similar errors. the same interpreter is also available at ideone.com
I wrote a simple (and very slow) interpreter for brainfuck here: pastebin.com/sFxDSB3X maybe we (as a community) could work on a better version for the bff interpreter.
