Fixed in 1.1.2.

Comment 3 PaX Team 2013-01-12 20:20:03 UTC

did you guys find out what ld.so tried to mprotect to rwx? i have the feeling that there's a better solution here than disabling mprotect on the binary...

I have a feeling that it's something with opencl, but I'm not sure.  I didn't test that deeply.
