This sounds like PR61737 (fixed; use 4.9.2 not released yet), but of course with the above sentence serving as your complete bug-report (or did I miss one?) that will only be a guess. > I'm using gcc 4.7.2, but of course, that is a locally built > version that might have patches not upstream > (although I doubt it knowing the gcc CRIS maintainer :-) (oops. *blush*) The TLS stuff is unfortunately not upstreamed at this time. Unimportant when building the kernel, but mentioned for completeness. (The bad excuse is that I originally awaited pre-v32 kernels to get the corresponding TLS support so I wouldn't have to do ugly pre-vs.-v32 conditionals, then the whole thing lost priority, and now I avoid adding code I can't/won't test - the glibc end isn't upstreamed either. Sorry.) brgds, H-P
