Comment bug in syntax highlighting?

In a recent SO question, the following code appeared:

# define v putchar
#   define print(x) main(){v(4+v(v(52)-4));return 0;}/*
#>+++++++4+[>++++++<-]> ++++.----.++++.*/
print(202*2);exit();
#define/*>.@*/exit()

There is something distinctly odd about the syntax highlighting of the last line, though:

See how a comment which is begun with a # appears to be ended by */? Even without knowing what language Prettify is assuming this code to be in (which is impossible to decide definitively in this case), this doesn't seem right, somehow. At least, I've never heard of any language with that comment syntax...
