[Tinyos-help] Compilation Error: section vectors overlap

[Eric Decker]

".text" is a strange (historical and I don't remember why) reference to code
space.  Rom/Flash etc.
You are overflowing the code space which is 48K.  Your previous program
48564 and then you added 100 lines of code and bam!

Are you compiling with the optimizer on?  If it is then you will have to
rework what your code is doing.
