bf2c @1.2.3 Most any program results in a bus error

[l2g@…]

In my tests, feeding anything but the most trivial Brainfuck program as input to this compiler ultimately results in a bus error.

$ bf2c -i calc.bf -o calc.c

(It's also interesting that the portfile says this is version 1.2.3 while bf2c itself says it's 1.2.2. The port really is grabbing the appropriate 1.2.3 tarball from Sourceforge.)

I'll attach a sample program that can be used as input. It's a quine (a program that generates itself as output).
