Speaking as a GDB developer here, you should really put some pressure on the GCC developers to stop doing unhelpful optimizations like this, instead of adding work-arounds like this. While ARM is the most prominent architecture affected by this, there are other architectures where noreturn messes up the backtraces from time to time. _______________________________________________ xorg-devel mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-devel
