Interpreter bug

There's a nice, subtle bug in the de-facto interpreter (, for the \ instruction. The backslash at the end of line 61 extends the // comment to also cover line 62, so the ++ptr; statement gets skipped, and as a result \ uses the wrong tape offsets, and implicitly moves the tape pointer left by one.

Offending code:

 } else if (current_char == '\\') { //Same as /, except popped, also, i used an excapecode here to get past \

(A \ at the end of a line is treated as a line-continuation character by C. You can see this in action in the syntax highlighting at pastebin.) FIXED in new version (
