Phew! Mystery solved! Verify attached patch. Trouble was that vector ChaCha subroutine relies on its alignment in memory. But on AIX it's impossible to *control* alignment with desired granularity without specifying higher alignment for .text segment itself. And .text directive was missing in chacha-ppc module :-( So it's not exactly optimizations of ppccap.o that mattered, but its changing size depending on optimization options that was affecting chacha subroutine's alignment. It actually *could* be vice versa, i.e. work with optimizations on and fail without, it's all about a coincidence. -- Ticket here: http://rt.openssl.org/Ticket/Display.html?id=4667 Please log in as guest with password guest if prompted
