I wrote one in C for the GPSD project that has two interesting properties:

(1) No use of malloc(),

(2) Unpacks to *fixed-extent* data structures.

It has one language restriction: Array subelements all have to be the same type.

It's not a stream parser, so there will be compile-time limits on the volume of data it can handle. This isn't a big deal in the GPSD context, where the objects are relatively short (< 1K) datagrams.

It's very well tested and, I think, pretty bulletproof. I've been thinking of spinning it out as a reusable project.
