Ouch! I never got the segfault on my side.
Here is the setup I am using: - OMAP4 Pandaboard, - 13.07 Ubuntu dist from http://www.linaro.org/downloads/, - 3.11 mainline kernel + 3 patches for unwinding info, - patched perf tool, - dbg flavor of the libs installed. Without them installed I do not get the address resolved but no segfaults Can you check if the linked libraries contain the .debug_frame sections? (ldd; readelf -S /lib/arm-linux-gnueabihf/libc-2.17.so|grep debug_frame; readelf -S /usr/lib/debug/lib/arm-linux-gnueabihf/libc-2.17.so|grep debug_frame)? > > Will Jean -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
