These two declarations are not compatible. The latter declares number as
a data symbol, but the former defines it is an absolute symbol. Thus what
you get is undefined behaviour.

Hi
I thought that .types do not care for linking, I never ran into problem
with different .types on symbols. BTW. if you look at assembler, there are
no .type directives regarding "number" at all.
How otherwise should external C variables be placed at absolute locations?
(I need variables and function on absolute locations quite often and I
always used this method)
