Bug ID: 471476 Summary: unhandled amd64-linux syscall: 441 Classification: Developer tools Product: valgrind Version: 3.21.0 Platform: Archlinux OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: cachegrind Assignee: n...@valgrind.org Reporter: ronnebaumfinan...@gmail.com Target Milestone: --- SUMMARY *** unhandled amd64-linux syscall: 441 I received this warning message when running the commands below. I ran the same command on a couple C programs after receiving the warning, and they all output the same message show below. The warning states that there is an unhandled amd64-linux syscall, specifying 441. I'm not very inclined when it comes to hardware, but I am on an intel cpu, so I'm curious as to why there would be an amd syscall. The programs that I ran the command on were compiled with the c89, c99, gcc, and clang compilers. All of the programs output the same warning message shown below. *** STEPS TO REPRODUCE 1. valgrind --tool=cachegrind ls -l ./<program> (cmd source: https://courses.cs.washington.edu/courses/cse326/05wi/valgrind-doc/cg_main.html) I get the following output after running the command: $ valgrind --tool=cachegrind ls -l ./<program> WARNING: unhandled amd64-linux syscall: 441 You may be able to write your own handler. Read the file README_MISSING_SYSCALL_OR_IOCTL. Nevertheless we consider this a bug. Please report it at http://valgrind.org/support/bug_reports.html.
