[email protected] changed: What |Removed |Added ---------------------------------------------------------------------------- Assignee|[email protected] |[email protected] --- Comment #3 from [email protected] --- It turns out this happens because FreeBSD does not allow user processes to change PSL_RF via ptrace(). It seems the sequence of events is 1) breakpoint or exception 2) lldb checkpoints thread state - ptrace(..., PT_GETREGS) returns rflags with PSL_RF set 3) expression is JITted and executed, leaving PSL_RF cleared in kernel thread state 4) lldb tries to restore checkpointed thread state via PT_SETREGS 5) ptrace() returns EINVAL due to attempt to change PSL_RF -- You are receiving this mail because: You are the assignee for the bug.
