I can't find commit d04dc94cc2b0141f06ed9de1665ab89a3f549e0b > > Similarly, if dwarf_get() reading of %rip succeeds for non-dward walker, > reset the ret to 1. The success value of 0 stops the iteration. This second part breaks test-ptrace on Linux. What if dwarf_get() returns 0? -Arun _______________________________________________ Libunwind-devel mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/libunwind-devel
