This is known. One return path is the normal return path, and one is the panic/recover return path. Each has a call to deferreturn. We don't share epilogues at the moment, see #24936 for some discussion.
In any case, this bug will probably become obsolete once we fix #14939.
But I'll leave this open for now. I couldn't find an issue explicitly about epilogue sharing (which this is), so might as well use this one.
