------- Additional Comments From neroden at gcc dot gnu dot org 2005-02-13 07:19 ------- Looking at the assembly generated for duplicate_insn_chain in cfglayout.c is the next step. (And the intermediate dumps, of course.) I'm highly suspicious, given that the code there features a switch inside a loop, that this is actually an instance of bug #18628.
