Valgrind Error: failed in UME with error 22

I am playing around with tool development in Valgrind and am getting the following error:

valgrind: mmap(0x8048000, 4096) failed in UME with error 22 (Invalid argument).
valgrind: this can be caused by executables with very large text, data or bss segments.

but my executable has nothing but simple variable assignments. I am not able to understand how to fix this problem. Any suggestions?

Solution

  • I solved this for my case and submitted a patch:

    https://bugs.kde.org/show_bug.cgi?id=290061

    If you or anyone else having this problem are building your executable with -pie, this might help you too.

    Update April 2025: the patch has been merged. It will probably be available in Valgrind 3.25.0 or 3.24.1.
