When prefixes such as struct, union, etc. are compared with the current type (e.g. struct foo), a comparison is made with the prefix. The code currently assumes that every type is a valid C type with a prefix, however at times, garbage ends up in this function causing an unpredictable crash with DTrace due to the isspace(*p) call or subsequent calls. An example that I've seen of this is the letter 's' being passed in, comparing true with struct as the comparison size was (q - p) == 1, but then we increment p with the length of "struct", resulting in an out of bounds read.
