Bug ID: 49899
Summary: lldb-shell :: Subprocess/clone-follow-parent*.test
failing on Linux/aarch64
Product: lldb
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: lldb-dev at lists.llvm.org
Reporter: mgorny at gentoo.org
CC: jdevlieghere at apple.com, llvm-bugs at lists.llvm.org
I don't have ARM64 hardware to debug this. The more important fork() tests
seem to pass, so I'm just going to 'unsupport' clone() tests on ARM64 Linux.
