The IBM Z system is funny because the backchain is inside the stack parameter region (reference: https://github.com/IBM/s390x-abi/blob/4e38ad9c8a883abc0ca248c2c6d51981ce7cbe02/lzsabi.tex#L2728), so if the backchain-saving logic is broken, the program itself is unaffected (since the parameter region will always have the backchain space, regardless of whether the backchain is enabled or not). The worst-case scenario is that blockchain data is invalid or missing, which will affect debugging tools that do not understand `eh_frame` data (which is in DWARF format). According to IBM, at least on Linux systems, these tools are extremely rare on s390x. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2082636 Title: [SRU] dpkg: backport frame-pointer enabling mechanism for Rust To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dpkg/+bug/2082636/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
