Two debug techniques: readelf -wf <binary> and look for pc=... range that matches the value of RIP you're trying to unwind from. If there is no unwind info, that's the problem. You can also use: ./configure --enable-debug UNW_DEBUG_LEVEL=16 test-program and post the output to the list or compare to a working test case (ones included in the test directory). -Arun _______________________________________________ Libunwind-devel mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/libunwind-devel
