Public bug reported:
bf has the feature to detect unbalanced brackets.
However, this fails to detect some types of unbalanced brackets.
For example, all of
$ bf <(echo '[')
$ bf <(echo '+[')
$ bf <(echo '[[]')
$ bf <(echo ']')
$ bf <(echo '[]]')
should say
Error: Unbalanced brackets.
an error occured
but they say nothing or
malloc(): memory corruption
Aborted (core dumped)
This is caused by a kind of off-by-one bug and a lack of checking.
Also, I wrote a patch for this bug and attached.
Package: bf
Version: 20041219ubuntu6
** Affects: bf (Ubuntu)
Importance: Undecided
Status: New
