OK looking at this a bit more, it turns out that Linaro hit this bug a month or two ago and added a *context implementation in glibc-ports: https://bugs.launchpad.net/qemu-linaro/+bug/883136 http://sourceware.org/ml/libc-ports/2012-02/msg00077.html Upstream: http://sourceware.org/git/?p=glibc-ports.git;a=commit;h=402a76b62dded0ee93cfec0471aaeccb989196d2 I'm a bit confused about the relationship of glibc, glibc-ports, Fedora and ARM. Can we include this patch in our glibc package to fix the bug in our qemu? I'd prefer a real implementation of the ucontext functions, instead of using the much less tested threads fallback code in qemu.
