The streaming decoder computed the code section start from the passed
"offset". That offset is computed from the module offset *after* the
number of functions has been read. Hence 1 is subtracted, with the
comment:
// The offset passed to {ProcessCodeSectionHeader} is an error offset and
// not the start offset of a buffer. Therefore we need the -1 here.
That subtraction of 1 worked when the number of functions was encoded in
a 1-byte LEB, otherwise it was off.
This CL fixes the immediate issue of passing the right code offset. The
usage of the previously existing offset also seems wrong, and I will try
to clean that up in a follow-up CL.
