Type promotion can lead to strange effects. While trptr++ seems like
a safe bet, I would not trust ++trptr...
Anyway, this apparently is a compiler or a dumper problem with the
local label. I have to get at the current address with a different
method, probably inline assembly. Pity.
Or construct a non-local label name from __LINE__.
