            Bug ID: 46093
           Summary: Posix/getrandom.c fails for 32-bit arm
           Product: compiler-rt
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: asan
          Assignee: unassignedbugs at nondot.org
          Reporter: diana.picus at linaro.org
                CC: llvm-bugs at lists.llvm.org

This fails in a cryptic way for asan, lsan and ubsan. Seen on llvm 10.0.1-rc1,
but IIUC not on llvm 10.0.0.
