OK, found it. The problem is in EH table entries like:
.uleb128 .LEHB8-.LCOLDB1
.uleb128 .LEHE8-.LEHB8
.uleb128 .L16-.LCOLDB1
.uleb128 0x1
Now the third entry is landing pad.

requiring an EH edge to finish properly while we predict EH edges are unlikely.
This is however partly undone by the hack in
