As does a make in that directory. But a > top-level make gives the random sometimes 0-length note sections. This sounds like memory corruption of some kind. I would suggest enabling memory debugging if you have that support available, or else adding some debugging of your own. > arm_add_note() gets called with the same parms for both zero & non-zero > cases. So what would cause the contents to disappear? Note - the arm_add_note() function was removed a while ago, so you may find that upgrading to newer binutils sources will solve this problem for you.
