If this is a know problem, nevermind... strip -x is broken in 041295-SNAP. An immediate symptom is that kernels that have been strip -x'ed won't boot. The problems seems to be an interaction between mmap'ed files and ftruncate. strip chews on a mapped file and ftruncates it. After the ftruncate, the first page of the file reverts to the original data that was in the file. I thought that it might have just been "undefined" to ftruncate a mapped file, but moving the call to ftruncate () after the call to munmap showed the same behavior. Tim
